Mac small business share nearly triples over the summer
By Aidan Malley
Tuesday, November 25, 2008, 03:30 pm PT (06:30 pm ET)
Even as many home buyers recently suddenly became shy about buying Apple computers in mid-year, small businesses just as quickly took to Macs —to the point where Apple's market share in that field grew three times larger almost overnight.
Reporting back to investors, Needham Co. analyst Charlie Wolf notes that Apple moved from selling just 61,000 Macs to small businesses in the spring to 188,000 in the three months of Apple's summer quarter ended in September.
The gain boosted Apple's share of the field from a modest 1.9 percent during the earlier season to a significant 5.6 percent in summer. It was enough to not only give Apple a new level of influence but also to carry the company through a tough period: where Mac shipments to regular home buyers suddenly cooled in growth from 53.6 percent quarter-to-quarter from the spring to just 9.1 percent in the summer, the small business spike represented nearly all of Apple's Mac growth at about 97 percent of systems leaving warehouses and shelves.
Such a rapid move is odd for Apple, which has often fought to make any headway in a normally Windows-dominated crowd; it's inexplicable enough that Wolf himself doesn't have a simplified answer.
"After years when the Mac's share of this market barely budged, the increase was so abrupt that there are no obvious explanations for it," he says.
The answer offered is instead a complex one based on Apple's long-term efforts. The cost-effectiveness of Mac OS X Server, Xserves, the Xsan storage system and Apple Remote Desktop all established a foundation but have themselves never made much of an impact.
It's rather a combination of software and retail that has given Apple the sudden rush of customers, the Needham researcher claims. With Boot Camp now a permanent feature as of Leopard and supported by the increasing use of Parallels Desktop and VMware Fusion —both of which can now run Mac OS X virtual machines as well as Windows and Linux —smaller companies can run a second operating system and ease the pain of converting some or all of their operations to the Mac platform.
Retail strategies are also seen helping the Mac's inroads. A large number of Apple retail shops now specifically include small business courses and also set aside greater resources as a whole just to these customers. That relatively new devotion to business has "begun to bear fruit," Wolf notes.
He also observes that Apple's sudden drop in overall growth during the summer, which also included education, is potentially just a very temporary glitch and hid an imminent rush.
While again the drop was mysterious enough to have no clear explanation, Wolf believes the flattened growth in Mac numbers may well have stemmed from customers waiting on expected new MacBooks that didn't ultimately ship until mid-October. This had a spring-loaded effect with sales in October compensating for the earlier drop.
Wolf further suggests the dip may have come from a sudden "fad" for netbooks that particularly affected students returning to college as well as concerns over then-high gas prices and recessionary fears.

A Republican Revolution. Kevin Annett Runs For Member of Parliament In Winnipeg North by William S Annett

A Republican Revolution: Kevin Annett Runs For Member of Parliament In Winnipeg North by William S. Annett
The New Canadian Shield Vol. 1, No. 1:
A Republican Revolution
Kevin Annett Runs For Member of Parliament In Winnipeg North
by William S. Annett
"To the folks in Kildonan, Eagle Strong Voice has spoke:
'Ere the Queen's crown go down there are crowns to be broke;
So each voting Canuck north of Portage and Main,
Should up the Republic, Liz's loss is our gain.'"
- The ghost of Louis Riel, Sung to the tune of Bonnie Dundee
___________
Canada is holding a Federal election some time in September, whenever the Prime Minister gets around to telling the Governor General to tell the Queen of England to tell the GG to tell the PM to drop a writ.
Writ dropping in the Great Pale North, unlike most other countries, means calling an election. In the Canadian Parliament, if the PM's majority suddenly isn't, a writ will get dropped, usually along with the dropper.
Prime Minister Justin Trudeau recently had no dropping choice, following his confession that squeaky clean Canada has been guilty of genocide, although of the nice kind, whereby you rub out the next generation instead of the current one, as they do in all those uncivilized countries.
In comparison, his Trump-like predecessor, Stephen Harper, in an effort to Make Canada Great Again, pointed out that killing 60,000 Indian kids in those free-tuition schools had merely been mistaken pedagogy, for which he apologized, so there was no need to drop a writ. No genocide, no colonial history, no writ written. Which brings us to Kevin Annett, who has more or less single handedly upset the whole Canadian apple cart called Guilt Free Genocide.
Kevin is not your usual Parliamentary candidate. For instance, he has impertinently declared that if elected he won't genuflect before That Woman in London. He also has observed that when another royal oddity called Charles No. 2 gave his drinking buddies all of the land north of Minnesota in 1670, the sorry fop was engaging in something more than impertinence himself.
This past week, during his Banned-in-Ottawa radio show called Here We Stand, Kevin Annett threw his hat in the ring, not only revealing his receding hairline but the birth of the Republican Party, whose title was hitherto believed to be a wholly-owned subsidiary of the Trump Empire.
The new party ain't exactly a Neocon-like Canadian version of Donny Boy. The Republican Party of Kanata's program reads like a cross between Oliver Cromwell and a latter day Rosa Luxemburg. Let's just say if the Party ever comes to power in Canada, Bankers and Anglican Bishops better find another place to sip their martinis.
Now we get it, about giving Das Boot to an antediluvian monarch. Most Canadians actually like the idea. But why has the former Reverend chosen the north end of Winnipeg as the launching pad for his campaign for the new Republic?
Easy. North Winnipeg is not only home to the best borscht in the country but it's the very epicenter of dissent in Canadian history. The 'hood is drenched in a rich radical tradition dating back to Louis Riel, a mixed-blood rebel whom the great but ambivalent Canadian people elected to Parliament and then promptly hanged. It's also home to the biggest and poorest urban native population outside Vancouver's downtown east side: Rev Kev's kind of folks. North Winnipeg is the city that never sleeps, because there aren't enough flophouses to go around.
Kevin Annett shares that rich heritage. Although he was born in Edmonton, he was conceived in St. Boniface and dedicated to the proposition that River Heights stock brokers and St. Vital mink farmers are created equal. Kev's ties to North Winnipeg reach back through the generations. The frugal bones of his maternal Scottish ancestors are housed in mausoleum solemnity in Kildonan Cemetery: the dispossessed folks who first came to the settlement the Cree locals called "dirty water", armed conveniently with their Highland malt distillation.
To make things even more titillating, North Winnipeg was also the incubus of Jacob Penner, the first Communist ever elected to public office in Canada - or North America, for that matter. His ascension was watched nervously by the royally-created RCMP, even though Penner's sinecure was a relatively harmless one as a city alderman. But his putsch was enough to make that most frightened nation to the south consider arming the undefended border eight decades before the Trumpian Great Wall.
As it turned out, Jake Penner's sole contribution to a Dictatorship of the Proletariat was his siring of his son Roland, who read law at the University of Manitoba and went on to become Attorney General in a tepidly progressive NDP government in the 1980's. Roland's own claim to fame was his breaking of the No Jews Allowed statute of Winnipeg's venerable Carleton Club in 1982 with the quip, "Let's see them keep out the Attorney General!". So let it not be said that Canadians aren't enlightened.
You can see that Rev Kev has a hard act to follow. But we're trusting in the general discontent of Winnipeggers and Canucks in toto, as well as Kevin's own Ojibway Indian name Eagle Strong Voice, given to him when he was adopted into that nation in where else but the north end of the 'Peg.
Kevin's candidacy may be there, but his campaign and his message will be national.
William Annett is an equally impertinent, 90 year old American who gave Kevin his lovely brown eyes one moonlit night on the banks of the Assiniboine River. He is currently in retirement in a Florida community for wayward thinkers where he campaigns on behalf of his son among the legions of Canadian Snow Birds who prefer Life, Liberty and the Pursuit of Daytona Beach suntan lotion to the moral rigors of Canada. Bill also fathered two other children but he likes Kevin better

Street Portraits. By Dawoud Bey.

Dawoud Bey is having a moment. It sure took a while — he's nearing 70, with a stack of prestigious fellowships under the belt — but the wait was worth it. Bey's sprawling retrospective An American Project opened recently at the Whitney in New York. It features several dozen prints, spread across multiple floors, encompassing his entire career, now stretching into its sixth decade. Technically this is the show's second stop since it opened at SFMoMA last year. But alas, COVID. SFMoMA was shut down for most of 2020. So for practical purposes, the Whitney exhibition is An American Project's public debut, a chance to hit reset and start over in New York, not far from Bey's childhood in Queens.
The pandemic reset may have been serendipitous, since it allowed the current show to open nearly concurrently with Dawoud Bey's new Mack book, Street Portraits. The monograph may be brand new but the photos aren't. Bey shot them between 1988 and 1991 — the supposedly "kinder and gentler" Bush years — mostly in Brooklyn, using a view camera with Polaroid 55 film. Visitors to the Whitney can see a handful of prints from the series tucked into one room, where they comprise a small part of An American Project. For the book, the selection has been expanded to include seventy photos. In just about every way — from observation to exposure to tonality to reproduction — the pictures are spectacular.
As the title implies, this series has the loose, providential quality of street photographs. Bey encountered his subjects in passing. There was no studio, no lighting, no prelude or courtship. There was simply May I take your portrait?, a quick snap, and then the next photo op. "The challenge of photographing in the street is to make it feel like the most natural thing," says Bey, "even though it clearly isn't." His exposures have the improvisatory freshness one might expect from a fleeting process, but also something else. They manage to sample just about all of humanity. There are old and young, men and women, wealthy and poor, singles and couples, lovers and misanthropes. Some are dressed in suits. Others in terry cloth. There's an albino, an athlete, a biker, a street worker, churchgoers and hip-hoppers. Comparisons to Sander's People of the Twentieth Century may be inevitable, and the standard of skill is similar. But Bey is less concerned with vocational identity than human connection.
There is also the important fact that all of his subjects are Black, as is Bey. Street Portraits is not so much a collection of pictures as it is a communal portrait of African-American life in a late 20th-century city. "History is the thing that I'm mostly preoccupied with," he says. "How can one imagine and visualize African American history, make that history resonate?" He's created an invaluable record. Street Portraits could slot as easily into a sociological museum as the Whitney.
Greg Tate's afterward places Bey into historic context, musing on the particulars of Black life and its photographic depiction. "Bey's portraits," he writes, "celebrate Blackfolk's uncommon carriage, forged under multigenerational pressure." Borrowing Cornell West's phrase postural semantics, Tate explains "we show up ready for the world adorned and armored with our mean lids, and even meaner leans." Perhaps one might read the bold stance of a girl with school medals as a mean lean. Or the immense chapeau of a woman on Fulton and Washington as a mean lid. Other photographs resist poetic phrasing, but they exude a similar penetrating quality. A woman sitting by her daughter stares up at Bey's lens with all of her might. A couple clutching near a road offers Bey their full attention before resuming their embrace.
Such images feel relaxed and natural, a million miles from the depictions of Black America which commonly circulated at the time: magazine photos of troubled thugs with weapons, crossed limbs, and saggy waistlines. Even the pictures of Janette Beckman and Jamel Shabazz, made in the same era with some sensitivity, strike a false note in comparison to Bey. They are too performative and artificial, offering a selective view of Black culture. Of course, all photography is selective and Bey's pictures are no exception. But somehow he's managed to broaden the net. His pictures seem an unfiltered sample of Black life — the "uncommon chosen people", to use Greg Tate's phrase — in 90s Brooklyn (a few photos are included from Rochester and DC).
The racial component of Street Portraits cannot be overlooked. But the book goes beyond that, and it's worth noting Bey's skill as a portraitist. His ability to connect with strangers and defuse their guard is uncanny. Without fail, every person in these photos looks directly at Bey's camera. "Blackfolk's eye-to-eye looking back game can meet any righteous or even reckless eyeballing judgement the world might bring," writes Tate. You'll find no cheesy mugging for the camera here. Perhaps those exposures have been excised? Or were never created? In any case, the frames selected are vulnerable and honest.
The choice of Polaroid Type 55 is adroit. The process created both a negative and positive, meaning that he could keep a record of each image, while offering a a print to his subjects. Perhaps they still circulate in some quarters, in family albums or on refrigerators? As for the negatives, their inky intensity and rich tones seem tailored for Black and Brown skin. Meanwhile, the brighter tones drift off into blank reverie. Bey's use of a view camera to create sharply contoured edges fronting bokehed backdrops brings his characters into relief, against familiar scenes of chainlink, porches, and sidewalks. Add in developing stains along the edges and the total effect is brilliant. These people from forty years ago appear animated and alive. Yet they cannot escape their photographic artifacts, trapped in alchemical ether like lightning in a bottle. All of the above has been superbly captured in book form by Mack, as is their custom. Cover, paper stock, tonality, and design are top-notch. It may have taken forty years for these pictures to surface in book form, but it was worth the wait.

Q: If Else condition for temporary table IF (@Track = 'SearchSelect')
BEGIN
    IF(@limitedAccess = 'true')
    BEGIN
        SELECT CusLst.CustomerId, MAX(CusCon.CustomerContactId) AS CustomerContactId
        INTO #CustomerList1
        FROM CustomerList CusLst
        LEFT JOIN CustomerContact CusCon ON CusLst.CustomerId = CusCon.CustomerId
        INNER JOIN CustomerUser ON CusLst.CustomerId = CustomerUser.CustomerId
        WHERE CustomerUser.UserId = @userId
        GROUP BY CusLst.CustomerId
    END
    ELSE
    BEGIN
        SELECT CusLst.CustomerId, MAX(CusCon.CustomerContactId) AS CustomerContactId
        INTO #CustomerList1
        FROM CustomerList CusLst
        LEFT JOIN CustomerContact CusCon ON CusLst.CustomerId = CusCon.CustomerId
        GROUP BY CusLst.CustomerId
    END

This is causing an error as customerList1 already exists. What to do if I want to fill temporary table based on the condition in my stored procedure?

A: Add this code before you start working
IF Object_id('tempdb..#CustomerList1') IS NOT NULL
BEGIN
      DROP TABLE #CustomerList1
END

A: EDITED:
You probably have created your temp table either remove your create table or use
INSERT INTO #customerlist1(columns)
SELECT columns
FROM customerlist

since this
SELECT CusLst.CustomerId, MAX(CusCon.CustomerContactId) AS CustomerContactId
    INTO #CustomerList1
    FROM CustomerList CusLst
    LEFT JOIN CustomerContact CusCon ON CusLst.CustomerId = CusCon.CustomerId
    INNER JOIN CustomerUser ON CusLst.CustomerId = CustomerUser.CustomerId
    WHERE CustomerUser.UserId = @userId
    GROUP BY CusLst.CustomerId

creates a new temp table that's why it throws an error.
https://www.w3schools.com/sql/sql_select_into.asp

A: First check your temp table exists or not in your database.IF exists means drop your temp table and then create new one.
IF EXISTS(SELECT 1 FROM tempdb.dbo.sysobjects WHERE xtype in ('U') AND id =
object_id(N'tempdb..#CustomerList1') )
      DROP TABLE #CustomerList1;

Yuri Andrukhovych was born on 13 March 1960 in IvanoFrankivsk, Ukraine. In 1982, he graduated from the Department of Editing at the Ukrainian Institute of Printing, where he studied journalism. He began to publish his poetry in literary journals in 1982. In 1985, together with Viktor Neborak and Oleksandr Irvaniets, Y. A. founded the popular literary performance group BuBaBu (BurlesqueBlusterBuffonery). This group was a seminal part of Ukrainian literary culture in the 1980 s, and its members continue to be active as writers.
Andrukhovych's first book of poetry Sky and Squares appeared in 1985. Military service in 1983 1984 inspired him to write a series of seven army stories, which were published in 1989. The life of a soldier in the Red Army was also the subject of his screenplay A Military March for an Angel (1989), which was used for A. Donchyk` s film Oxygen Starvation (1991).
From 1989 until 1991, Yuri Andrukhovych studied at the Maxim Gorky Literary Institute in Moscow, where he was enrolled in Advanced Literary Courses. At the same time, he published two other books of poetry: Downtown (1989) and Exotic Birds and Plants (1991, new edition 1997).
Andrukhovych's prose works, the novels Recreations (1992, new edition 1997), Moscoviada (1993, new edition 1997) and Perversion (1996, new editions 1997, 1999), had a great impact on readers in the Ukraine and abroad. Andrukhovych has participated in several international festivals and meetings for writers, for example: the Lahti Writer's Reunion, Finland, 1997, and the Toronto Harbourfront Reading, Canada, 1998.
In November 1998, he was invited by American universities, including Harvard, Yale, Columbia, The Pennsylvania State University and La Salle University, to give literary readings.
Yuri Andrukhovych's literary works have received several awards: Blahovist (1993), the award of the Helen ShcherbanLapika Foundation (1996), the Novel of the Year Prize from the prominent literary journal Suchasnist (1997), and the Lesia & Petro Kovalev Award (1998). His works have been translated and published in Poland, Canada, USA, Germany, Hungary, Austria, Russia and Finland.
...Andrukhovych is a master of including the reader into his tale. A each character stumbles into increasingly surreal surroundings, the reader is transported into the scenes with them. Nemyrych and Shtundera, each in his own way, discovers a part of the past in this little village of Chortopil. It is a past that is dark, even frightening. Martofliak grapples with alcoholism and Khoma with personal loyalty.
If you re looking for international writing free of the obvious touchstones of contemporary Western lit, Eastern Europe is a good place to start. This year's modest IFOA crop includes Russian expatriate Andrei Makine and Ukrainian postmodernist Yuri Andrukhovych. Makine (who lives in Paris and now writes in French) was the first writer to win both of France's major literary awards the Prix Goncourt and the Prix Medici for the same book, a lyrical (and politically frank) autobiographical novel entitled Dreams of My Russian Summers (since then translated into 25 languages).
Karbido, Yuri Andrukhovych. Samohon. (special Ukrainian release).
Finally, we have it – the Ukrainian release of the joint album by Yuri Andruhovych and the researchers into psycho-music from Karbido group saw the light of the day. A strange mixture of ethno-jazz, dub, avant-garde rock and ironically sarcastic melodic recitals – no, this list of ingredients, in actual fact, explains nothing. One should listen to it – and this, at least, should once be heard. Better – more than once.
The book by Yuriy Andrukhovych – the most renowned modern Ukrainian postmodernist writer and the Patriarch of "Bu-Ba-Bu" – includes "canonical" poems from all of his collections, as well as the famous series "Letters to Ukraine". This is the most complete publication of selected pieces by the poet today.
Karbido, Yuri Andrukhovych. Absinthe. /super-pack/. (CD+DVD).
...a mysterious story of Stanislaus Perfecki – a poet, a traveler, and a performer who embarks upon a journey from Lviv to the West, and ultimately emerges in Venice, the City of Ghosts. There, he experiences a series of incredible adventures and falls in love with Ada Cytryna, his interpretress. Being forced to part with his beloved woman and unable to fulfil his special top secret mission, Perfecki vanishes..

\vspace{2mm}

The 23 processes included in S{\small USY23} are listed in Table 2.
In the heading, 'abbrev.' and 'dir.' stand for the
abbreviated name used in the control card and directory
name where the generated code is stored, respectively.
In Tables 3 $\sim$ 9, decay modes taken into account in the
unstable sparticle decays in S{\small USY23} are listed.
By default, each branching ratio is automatically calculated
in the framework of the MSSM.
The abbreviated names are used in the control card or {\it kinit.f}
when users want to set each branching ratio ({\tt jbrnch = 1}).

\section{Appendix. Installation}
\leftline{\large\bf Appendix D. Installation}

The source code  is available by {\tt anonymous ftp} from
{\tt ftp.kek.jp} in the directory \\ {\tt kek/minami/susy23}.
The S{\small USY23} system contains the complete set of Fortran sources
for 23 processes, the three libraries, i.e.,
{\tt BASES/SPRING}, {\tt CHANEL} and
utilities for kinematics.
Those source codes are written in FORTRAN77.
In addition, S{\small USY23} provides the
interface program to generate a few Fortran source files
according to the control data specified by the user.
This program is written in C, YACC and LEX.
S{\small USY23} has been developed on HP-UX, but should run on
any UNIX platform with a fortran complier.

The procedure of installation is as follows:
\begin{enumerate}
\item Editing {\it Makefile}.

The following macros in {\it Makefile} should be taken care of by
users themselves.
For example, {\tt SU23DIR} defines the directory name
where S{\small USY23} is installed.
The values of {\tt FC} and {\tt FOPT} define the relevant compiler
name and option for your system.
The other macros can be left as they are.

\begin{tabular}{lcl}
  {\tt SU23DIR} &{\tt =}& directory where S{\small USY23} are installed. \\
  {\tt PRCDIR}   &{\tt =}& directory where process files are installed. \\
 & &  (default is \verb+$(SU23DIR)/prc+.) \\
  {\tt LIBDIR}   &{\tt =}& directory where libraries are installed. \\
 & &  (default is \verb+$(SU23DIR)/lib+.) \\
  {\tt BINDIR}   &{\tt =}& directory where an executable is installed. \\
 & & (default is \verb+$(SU23DIR)/bin+.) \\
  {\tt MACHINE} &{\tt =}& {\tt [hpux|hiux|sgi|dec|sun]} \\
  {\tt FC}      &{\tt =}& FORTRAN compiler command name. \\
  {\tt FOPT}    &{\tt =}& FORTRAN compiler options. \\
  {\tt CERNLIBS} &{\tt =}& CERNLIB including the jetset library. \\
& & For HP-UX, \verb+-L/cern/pro/lib -ljetset74+ \\
& & \verb+-lpacklib -lkernlib -L/lib/pa1.1/ -lm+ \\
\end{tabular}

\item Compilation.

  By executing command {\tt make install} the executable of the interface
  program({\tt susy23}) is generated at {\tt BINDIR}.
  Furthermore six libraries, {\tt BASES/SPRING}, {\tt CHANEL},
  kinematics utility library and three susy libraries,
  are generated in {\tt LIBDIR}.

\end{enumerate}

The sample control data files will be found in the directory
{\tt sample}.

\section{Introduction} \label{introduction}

The supersymmetric (SUSY) standard model \cite{Nilles} is the most
promising extension of the standard model (SM)
as it could naturally give a solution
to the gauge hierarchy problem.
In SUSY model, thanks to the symmetry between bosons and fermions,
the quadratic divergences are genuinely cancelled out.
The price to pay is the existence of a large number of new particles,
SUSY particles (sparticles),
yet to be discovered.
The most impressive evidence in favor of SUSY may be
the unification of gauge couplings in SUSY Grand Unified
Theories (GUTs) \cite{running}.
The Lightest SUSY Particle (LSP) is often proposed as a candidate
to the missing mass in the Universe for the cold component of the
so-called dark matter \cite{dm}.
Many peoples consider the "SUSY world" as a plausible scenario
for future particle physics prompting the need of event generators.

Although the gauge hierarchy issue set a mass upper bound to SUSY
particles of $O$(1TeV), lighter sparticles are seen as giving more
natural solution.
So there is a possibility that the sparticles could
be discovered at LEP2 in electron-positron collision.
While the hadron colliders such as FNAL Tevatron and DESY HERA
have already covered
larger scattering energies, LEP2 could be the first machine
to discover ``light'' sparticles (the chargino,
the slepton or the stop) as the background conditions are far better in
electron-positron than in hadron colliders.

{S{\small USY23}} is an event generator suitable for
detector simulation and data analysis dedicated to
SUSY processes in the LEP2 energy range.

It is based on the {\tt GRACE} \cite{grace,gracesusy} system
which generates
automatically the matrix element in terms of helicity amplitudes
(supplied by the {\tt CHANEL} \cite{chanel} library) for
any processes once the initial and the final states have been specified.
In addition,
a kinematics library has been developed
for each process topology
(weeding out multidimensional singularities) for a better
convergence of the Monte-Carlo integration over the phase
space.

The {S{\small USY23}} package is actually a collection of 23 types of
SUSY processes at $e^+e^-$ colliders,
consisting of 18 final 2-body and 5 final 3-body
processes, presented in a coherent and
uniform environment.
These processes are

Once a process has been selected, the total and differential cross
sections are computed
with the Monte-Carlo integration package {\tt BASES} \cite{bases}.
Then {\tt SPRING} \cite{bases}, a general purpose event generator,
provides unweighted events.
Some physics results have already been presented in
ref.\cite{ours}.

The matrix element generated by {\tt GRACE} corresponds
to the genuine tree level process in the massive case.
Initial state radiation corrections,
unstable sparticle decays and hadronization
must then be introduced to produce realistic event generation.
All of them have been implemented in {S{\small USY23}}.

For the initial state radiation (ISR) two techniques are provided
in the program.
\footnote{ISR is not available for the hard photon process, i.e.,
{\mbox{$e^{-}e^{+} \rightarrow \gamma \chi^{0}_1 \chi^{0}_1$.}}}
The first one uses the well-known analytic form of $e^\pm$ structure
function \cite{kuraev}
and the second is based on {\tt QEDPS} \cite{isr}, a radiative correction
generator
producing an indefinite numbers of photons according to the parton
shower algorithm in the leading-logarithmic (LL) approximation.
Originally this
algorithm has been developed to simulate QCD parton shower.
One important point here is that {\tt QEDPS} reproduces
the radiative photon transverse momentum distributions.

Sparticle widths and decay branching ratios
are calculated
(see Tables 3$\sim$8 in Appendix C).
Each final state is then generated according to
the branching ratios.
In the present version, 2-body and 3-body direct decays as well as
some possible cascade decays are included.
Note that helicity informations of matrix elements
of the direct decays of inos
\footnote{We use ino as a generic name to represent neutral (neutralinos)
and charged (charginos) mixtures of gauginos and higgsinos.}
are taken into account in evaluating their decays.

We assume that the hadronization of partons can be separated
from the hard interaction studied here.
Under this assumption, the calculation of cross sections is
exact in {S{\small USY23}}.
Final state parton hadronization is performed, in {S{\small USY23}},
through the  mechanism  implemented in
{\tt JETSET} \cite{jetset}.

This paper is organized as follows.
MSSM basics is given in section~2.
The structure of the program is discussed in
section~3.
In section 4, all details about
running the program are presented.
A summary of the paper can be found in section 5.
Four appendices describe the parameters and options
which can be changed by the user, the list of all processes and the
program installation procedure.

\leftline{\large\bf 2.1 Particle content}
\smallskip

The Minimal SUSY Standard Model (MSSM)  includes the {\it minimal} particle
content.
That is, there should be at least one new particle (sparticle) for each
known particle in the SM and the two Higgs doublets.
The additional Higgs doublet must be included in order to
give mass to the up- and down-type quarks and to allow for the chiral
anomaly cancellation \cite{Nilles}.

For quarks and charged leptons there exist two scalar
partners per species, while for neutrinos there exists
one scalar partner per species.
These scalars are called squarks and sleptons, or, generically, sfermions.
Before SU(2)$\times$U(1) breaking, the left- and right-sfermions
do not mix since they have different SU(2)$\times$U(1) quantum numbers.
After the breaking, however, they can mix with each other.
In this case the mass eigenstates are parametrized by a mixing angle $\theta_f$ ;
\begin{equation}
\left({\widetilde f_1\atop\widetilde f_2}\right)=
\left(
{\widetilde f_{L}\,\cos\theta_f+\widetilde f_{R}\,\sin\theta_f}
\atop
{-\widetilde f_{L}\,\sin\theta_f+\widetilde f_{R}\,\cos\theta_f}
\right).
\end{equation}
Actually this mixing effect is substantial only for the third-generation
sfermions, especially for the stops (superpartners of the top quark)
owing to the large top mass \cite{stop}.

The new fermions are either the superpartner of spin-1 gauge bosons
(gauginos) or that of spin-0 bosons (higgsinos).
They mix each other when SU(2)$\times$U(1) symmetry is broken.
The mass eigenstates (inos) are usually mixtures of gaugino and
higgsino states.
They are called neutralinos
{\mbox{$\chi^0_k$}} ($k=1\sim4$)
and charginos {\mbox{$\chi^{\pm}_i$}} ($i=1,2$), respectively,
according to their electric charges.
Gluinos $\widetilde g$ are free from mixing
since the color SU(3) is not broken.
As usual, we consider the lightest neutralino $\chi^0_1$ as
the lightest sparticle (LSP).

MSSM contains two Higgs doublets and
five physical Higgs bosons
are left after SU(2)$\times$U(1) breaking \cite{higgs}.
They are two CP even ($h^0$, $H^0$),
one CP odd ($A^0$) neutral scalars and
two charged scalars ($H^\pm$).

The list of sparticles in the model is shown in Appendix A,
where the abbreviated particle names used in the control card and
the KF-codes assigned for each sparticles in {S{\small USY23}} are also
 shown.

\medskip
\leftline{\large\bf 2.2 Basic parameters of MSSM}
\smallskip

The standard model has 18 fundamental parameters to be determined
by experiments.
The MSSM has a somewhat larger number of parameters.
They are classified as
({\romannumeral 1}) gauge couplings,
({\romannumeral 2}) superpotential parameters and
({\romannumeral 3}) soft-breaking parameters.
In the following, we adopt the notation of the SUSY parameters described
in ref.\cite{Hikasa}.

\medskip
\leftline{\large\bf 2.2.1 gauge couplings}
\smallskip

The three gauge coupling parameters corresponding to
SU(3), SU(2) and U(1) gauge groups are the same as in the SM.
All gauge interactions are governed by these couplings.
They determine the fermion-sfermion-gaugino interactions
and four-point scalar interactions as well as ordinary
fermion-fermion-gauge-boson interactions.

\medskip
\leftline{\large\bf 2.2.2 superpotential parameters and $R$-parity}
\smallskip

In the MSSM, ordinary Yukawa interactions are generalized using the
superpotential $W(\hat{\phi})$, where $\hat{\phi}$ denotes arbitrary
chiral superfield \cite{Nilles}.
Renormalizability restricts the functional form of the superpotential to
\begin{equation}
W(\hat{\phi})=m_{ij}\hat{\phi}_{i}\hat{\phi}_{j}
+\lambda_{ijk}\hat{\phi}_i\hat{\phi}_j\hat{\phi}_k.
\end{equation}
The parameters $m_{ij}$ and $\lambda_{ijk}$ are further constrained by
the gauge symmetry and some discrete symmetries.

Later, we use the notation $\mu$ which is
a coefficient of the term quadratic in Higgs superfields
and contributes to
the mass terms of higgsinos and Higgs bosons \cite{Hikasa}.

A  well-known discrete, multiplicative symmetry is the $R$-parity
defined by
\begin{equation}
R=(-)^{3(B-L)+2S},
\end{equation}
where $B$, $L$ and $S$ stand for the baryon number,
the lepton number and the spin, respectively.
This formula implies that all ordinary SM particles
have even $R$-parity, whereas the corresponding superpartners
have odd $R$-parity.
Usually we impose the $B-L$ conservation on the MSSM
and then the MSSM possesses the $R$-parity invariance.
In {S{\small USY23}} only $R$-parity conserving processes are
considered.

\medskip
\leftline{\large\bf 2.2.3 soft-breaking parameters}
\smallskip

SUSY is not an exact symmetry of nature
since our world is not manifestly supersymmetric.
In the MSSM the SUSY breaking is induced by the soft-SUSY breaking
terms, which do not introduce quadratic divergences.
Hence the solution of the naturalness problem remains intact.
There are four types of soft breaking terms ;
(1)  gaugino masses $M_i$  ($i=1\sim3$),
(2)  masses for the sfermions $\widetilde{m}_{f}$,
(3)  trilinear term  $A_f$ and
(4)  three Higgs mass terms.
 The three mass parameters in the last item
 can be re-expressed in terms of
 two Higgs vacuum expectation values, $v_1$ and $v_2$, and
 one physical Higgs mass.
 Here $v_1$ and $v_2$ respectively denote the vacuum expectation values
 of the Higgs field coupled to $d$-type and $u$-type quarks.
 $v_1^2 + v_2^2$ $=$ (246 GeV)$^2$ is determined from
 the experimentally measured $W$-boson mass,
 while the ratio
 \begin{equation}
 \tan\beta = {\frac{v_2}{v_1}}
 \end{equation}
 is a free parameter of the model.

 A generally accepted assumption is that
 all the three gaugino mass parameters $M_i$ are equal at some
 grand unification scale $M_X$.
 Then the gaugino mass parameters can be expressed in terms of
 one of them, for instance, $M_2$.
 The other two gaugino mass parameters are given by
 \begin{eqnarray}
 M_1 &=& {\frac{5}{3}}\tan^2{\theta_{W}} M_2 \\
 M_3 &=& {\frac{\alpha_3}{\alpha}}\sin^{2}\theta_{W} M_2,
 \end{eqnarray}
where $\alpha$ and $\alpha_3$ ($=\alpha_s$) denote the QED and the QCD
coupling constants, respectively.

The trilinear terms $A_f$ appear in off-diagonal elements of the
mass matrix for sfermions($\widetilde{f}_L$, $\widetilde{f}_R$).
Consequently, it has direct relation to the mass eigenvalues
($m_{\widetilde{f}_1}$, $m_{\widetilde{f}_2}$)  and
the mixing angle $\theta_f$.
In our formulation, $A_f$'s ($f=t, b, \tau$) are
determined by those mixing parameters (see Eqs.(19), (20) and (21)).

\medskip
\leftline{{\large\bf 2.3 MSSM parameters in} {S{\small USY23}}}
\smallskip

In Appendix B, the input MSSM parameters in {S{\small USY23}} are listed.
They are
\begin{itemize}
\item[i)]  gaugino parameters, ($\tan\beta$, $M_2$, $\mu$),

in the 1st and 2nd generations,
($m_{\sel}$, $m_{\ser}$ ), ($m_{\sml}$, $m_{\smr}$ ),

\end{itemize}

From the above inputs,

{S{\small USY23}},

\begin{eqnarray}
{\mbox{$\chi^-_{1L}$}} &=&
{\widetilde{W}}^-_L \cos\phi_L +
{\widetilde{H}}^-_{1L} \sin\phi_L, \\
{\mbox{$\chi^-_{2L}$}} &=&
- {\widetilde{W}}^-_L \sin\phi_L +
{\widetilde{H}}^-_{1L} \cos\phi_L, \\
{\mbox{$\chi^-_{1R}$}} &=& {\widetilde{W}}^-_R \cos\phi_R
+ {\widetilde{H}}^-_{2L} \sin\phi_R, \\
{\mbox{$\chi^-_{2R}$}} &=& \epsilon_R
( - {\widetilde{W}}^-_R \sin\phi_R +
{\widetilde{H}}^-_{2L} \cos\phi_R ),
\end{eqnarray}

\item[iii)] the gluino mass $m_{\gluino}$ ($=M_3$) using Eq.(6),

\item[iv)] $m_{\snel}$ and $m_{\snmu}$ are calculated by the following relations:
\begin{eqnarray}
m_{\snel}^{2} &=&
m_{\sel}^{2}  -m_{e}^{2} + m_{W}^{2}\cos2{\beta}, \\
m_{\snmu}^{2} &=&
m_{\sml}^{2}  -m_{\mu}^{2} + m_{W}^{2}\cos2{\beta}.
\end{eqnarray}

\item[v)] $m_{\sdl}$ and $m_{\ssl}$ are calculated by the following relations:
\begin{eqnarray}
m_{\sdl}^{2} &=& m_{\sul}^{2}  -m_{u}^{2} +m_{d}^{2} - m_{W}^{2}\cos2{\beta},
  \\
m_{\ssl}^{2} &=&
m_{\scl}^{2}  -m_{c}^{2}
  + m_{s}^{2} - m_{W}^{2}\cos2{\beta},
\end{eqnarray}

\item[vi)] $m_{\stau_{2}}$  is given by:
\begin{eqnarray}
m_{\sntau}^{2} &=&
\cos^2{\theta_{\tau}}m_{\stau_{1}}^{2}+ \sin^2{\theta_{\tau}}m_{\stau_{2}}^{2} -m_{\tau}^{2}
+ m_{W}^{2}\cos2{\beta},
\end{eqnarray}

\item[vii)] $m_{\sbh}$  is given by:
\begin{eqnarray}
\cos^2{\theta_{t}}m_{\stl}^{2}+ \sin^2{\theta_{t}}m_{\sth}^{2} -m_{t}^{2} &=&
\cos^2{\theta_{b}}m_{\sbl}^{2}+ \sin^2{\theta_{b}}m_{\sbh}^{2} -m_{b}^{2}
+ m_{W}^{2}\cos2{\beta},
\end{eqnarray}

\item[viii)] the trilinear term  $A_f$ using formulae as follows
\begin{eqnarray}
A_t&=&-{\frac{1}{2}}\sin{2\theta_t}{\frac{m^2_{\widetilde{t}_2}-m^2_{\widetilde{t}_1}}
{m_t}}-\mu\cot{\beta} \label{tpara} \\
A_b&=&-{\frac{1}{2}}\sin{2\theta_b}{\frac{m^2_{\widetilde{b}_2}-m^2_{\widetilde{b}_1}}
{m_b}}-\mu\tan{\beta}, \label{bpara} \\
A_\tau&=&-{\frac{1}{2}}\sin{2\theta_\tau}{\frac{m^2_{\widetilde \tau_2}-m^2_{\widetilde \tau_1}}
{m_\tau}}-\mu\tan{\beta}, \label{apara}
\end{eqnarray}

\end{itemize}

Here we briefly discuss the relation between
our input parameters and those adopted in the
{\tt susygen} program \cite{susygen}.
As for the gaugino parameters, the sign convention of $\tan\beta$ and
$\mu$ is different. We use the positive definite $\mu$ and
$\tan\beta$ can have either positive or negative values.
In  {\tt susygen}, on the other hand, positive definite $\tan\beta$
and positive or negative $\mu$ are adopted.
As there exits a symmetry for the sign of $\tan\beta$ and $\mu$
in the MSSM,
the negative $\mu$ in {\tt susygen} corresponds to the negative
$\tan\beta$ in {S{\small USY23}}.
The definition of gaugino mass $M_2$ is the same in both generators.
As for the left-right mixing of sfermions in the 3rd generation,
we take observable masses and mixing angles,
($m_{\widetilde{f}_1}$, $m_{\widetilde{f}_2}$, $\theta_f$),
as inputs.
In {\tt susygen}, on the other hand, more basic model parameters
($m_{\widetilde{f}_L}$, $m_{\widetilde{f}_R}$, $A_f$) are adopted.
The relation between them can be found from
Eqs.(\ref{tpara}) $\sim$ (\ref{apara}) and the following formula,
\begin{equation}
m^{2}_{{\widetilde{f}_1}\atop{\widetilde{f}_2}}
         ={\frac{1}{2}}\left[ m^{2}_{\widetilde{f}_{L}}+m^{2}_{\widetilde{f}_{R}}
             \mp \left( (m^{2}_{\widetilde{f}_{L}}-m^{2}_{\widetilde{f}_{R}})^{2}
            +(2a_{f}m_{f})^{2}\right)^{1/2}\right],
\label{sfmass}
\end{equation}
where $a_t = -(A_t + \mu\cot\beta)$, $a_b = -(A_b + \mu\tan\beta)$ and
$a_{\tau} = -(A_{\tau} + \mu\tan\beta)$.
We did not impose low energy mass relations between masses of sfermions
determined by the renormalization group equations in some SUSY GUTs
because such mass relations sensitively depend on details of a model and
boundary conditions for model parameters at the unification scale.
In {\tt susygen}, however, there is an option for the calculation in the
framework of the minimal supergravity model \cite{Hikasa}.
In this model, masses of all sfermions in the 1st and 2nd generations are
determined by an input parameter, $m_\infty$ ($= m_0$),
which is the universal soft scalar mass at the unification scale.
For convenience of the users,
we present an example of relations between observable masses
and the parameter $m_\infty$
for the case of $\sin^2\theta_W$ $=$ $0.230$,
\begin{eqnarray}
m_{\sul}^2 &=& m^2_\infty + 7.26M^2_\infty + m^2_u
     + ({\frac{1}{2}}-{\frac{2}{3}}\sin^2\theta_W) m^2_Z \cos{2\beta}, \\
m_{\sur}^2 &=& m^2_\infty + 6.83M^2_\infty + m^2_u
     + {\frac{2}{3}}\sin^2\theta_W m^2_Z \cos{2\beta}, \\
m_{\sdr}^2 &=& m^2_\infty + 6.78M^2_\infty + m^2_d
     - {\frac{1}{3}}\sin^2\theta_W m^2_Z \cos{2\beta}, \\
m_{\sel}^2 &=& m^2_\infty + 0.530M^2_\infty + m^2_e
     - ({\frac{1}{2}}-\sin^2\theta_W) m^2_Z \cos{2\beta}, \\
m_{\ser}^2 &=& m^2_\infty + 0.1515M^2_\infty + m^2_e
     - \sin^2\theta_W m^2_Z \cos{2\beta},
\end{eqnarray}
where $M_\infty$ $=$ $1.22 M_2$ denotes the universal soft gaugino mass
at the unification scale.

\subsection{Radiative corrections} \label{radiative}
In the first approach, the simple electron structure function
is used.
The electron structure function at
$O(\alpha^2)$~\cite{kuraev}  which is to be
convoluted with the cross section for a primary
process is given by
\begin{eqnarray}
  D(x,s)&=& \left[1+{3\over8}\beta
 +\left({9\over128}-{\zeta(2)\over8}\right)\beta^2\right]
                 {\beta\over2}(1-x)^{\beta/2-1} \nonumber \\
    && -{\beta\over 4} \bigl( 1+x \bigr)
        -{\beta^2 \over 32} \biggl[ 4(1+x)\ln(1-x)
              +{1+3x^2 \over 1-x}\ln x+(5+x) \biggr],
                    \label{eq:Dxs} \\
\beta&=&(2\alpha/\pi)(\ln(s/m_e^2)-1),
\end{eqnarray}
where $s$ is the square of the total energy of the system and $x$ is
the momentum fraction of the electron.
Compared with the exact $O(\alpha)$ calculation for
$s$-channel annihilation,
the corrected cross section obtained by this function
does not contain the so-called $K$-factor:
\begin{equation}
1+{\alpha\over\pi}\left({\pi^2\over3}-{1\over2}\right)=1.006480\cdots.
\label{eq:kfact}
\end{equation}
This factor is not included since it is sensible only when the
$s$-channel $e^+e^-$ annihilation takes place.

The basic assumption of the QED Parton Shower method, {\tt QEDPS}
\cite{isr},
is primarily based on the fact that $D(x,Q^2)$ obeys the
Altarelli-Parisi equation, which can be expressed by the integral
equation
in the leading-logarithmic(LL) approximation
\begin{equation}
D(x,Q^2)= \Pi(Q^2,Q_s^2)D(x,Q_s^2)
+{\alpha\over2\pi}\int\nolimits_{Q_s^2}^{Q^2}{dK^2\over K^2}
    \Pi(Q^2,K^2)\int\nolimits_x^{1-\epsilon}{dy\over y}
           P(y)D(x/y,K^2),       \label{eq:intform}
\end{equation}
where the small quantity $\epsilon$ is a cutoff related with the
infrared singularity \cite{ll} and it will be defined later.
In this equation $P(x)$ is the split function noted $P_+(x)$
when regularized at $x=1$.
$Q_s^2$ is the initial value of $Q^2$ and a free parameter(of order
$m_e^2$).
For simplicity the fine structure constant $\alpha$ is assumed not
running with $Q^2$.
The Sudakov factor $\Pi$ is given by:
\begin{equation}
 \Pi(Q^2,{Q'}^2) = \exp\left(- {\alpha\over 2 \pi} \int_{{Q'}^2}^{Q^2}
 { d K^2 \over K^2} \int_0^{1-\epsilon} d x P(x) \right).
  \label{eq:non}
\end{equation}
and denotes
the probability that an electron evolves from ${Q'}^2$ to
$Q^2$ without emitting hard photon.

The integral equation (\ref{eq:intform}) can be solved by iteration.
It is clear that
the emission of $n$ photons corresponds to $n$ iterations. Hence
it is possible to regard the process as a stochastic mechanism
suggesting the shower algorithm in Ref.~\cite{isr}.

Once an exclusive process is fixed by the algorithm, each branching of
a photon is a real process, that is,
an electron with $x,K^2$ decays as:
    $ e^-(x,-K^2)\to e^-(xy,-{K'}^2)+\gamma(x(1-y),Q_0^2)$.
Here $Q_0^2$ is a cut-off to avoid the infrared divergence
and $\epsilon$ is given by $\epsilon = Q_0^2 / {K'}^2$.
The momentum
conservation at the branching gives:
$ -K^2=-{K'}^2/y+Q_0^2/(1-y)+{\bf k}_T^2/(y(1-y)) $
which in turn determines the photon transverse momentum relative to
the parent, ${\bf k}_T^2$, from $y,K^2,{K'}^2$.
This technique gives the ${\bf k}_T^2$ distribution as well as
the shape of the $x$-distribution.

The above algorithm concerns the
case where either $e^-$ or $e^+$ radiates photons
when the axial gauge vector is chosen along the momentum of the other
electron, namely $e^+$ or $e^-$. In the program, however, we
use the double cascade scheme to
ensure the symmetry of the radiation between $e^+$ and
$e^-$~\cite{double}. These two are mathematically
equivalent in the LL approximation.

\end{description}
We assume that squarks
in the first and second generations and the gluinos are sufficiently
heavy to forbid the charginos, neutralinos, sleptons,
stop and sbottom decays in these channels.
These are natural assumptions
as long as one deal with production processes of
the sparticles with mass ${\stackrel{<}{\sim}} 100$GeV in
the LEP2 energy regions.

In S{\small USY23} system, the masses are inspected  whether
the decay is possible or not.
\footnote{
Users must be careful in taking the input mass parameters so that
the lightest neutralino $\chi^0_1$ (LSP) should be lighter than
charginos and sfermions.}
When the channel is open, the decay width is computed.

\medskip
\leftline{\large\bf 3.2.2 Spin correlations}
\smallskip
The helicity informations of matrix elements in the fermionic
2-body and 3-body decays of the lighter chargino ${\chi^{-}_1}$ and
the second lightest neutralino ${\chi^{0}_2}$ are used
in the event generation of their decay products. In other words
kinematical distribution of the decay products is sensitive to
spin correlations with the mother ino.
All decay matrix elements are computed exactly
with {\tt GRACE} \cite{grace} in tree approximation.

In the event generation step,
the helicity state of inos is
selected
by the Monte-Carlo method  based on the
relative cross sections of all possible helicity combinations.
Four-momentum vectors of daughter-particle are
determined by the decay matrix element of the
ino with specified helicity.

\section{Structure of the program} \label{structure}
\medskip
\leftline{\large\bf  4. Structure of the program}
\smallskip

The {S{\small USY23}} provides event generation for
twenty-three SUSY processes as listed in Table 2 in Appendix C,
at $e^+e^-$ colliders  with or without radiative corrections.
As is shown in Appendix B,
there are many options covering theoretical and experimental
requirements.
Since all program components are  distributed as source code,
users can select all options
by editing the relevant subprograms directly.
However,
an interface program {\tt susy23} is prepared
to lighten the user's burden.
\footnote{
Please do not confuse the executable module named
{\tt susy23} with the S{\small USY23} system itself.
}
It selects and/or corrects the program code which are
affected by the various
options and it creates a ``{\tt Makefile}'' according to the user
requirements.
This procedure is called the source generation phase.

In the integration step, the matrix element of a selected
process is integrated over the phase space
by the subprogram {\tt BASES},
which gives the total and differential cross sections and
the probability distribution
used in the event generation phase \cite{bases}.
There, the subprogram {\tt SPRING} samples a point
in the phase space and test if it can be accepted as a new event
according to its probability.
When an event is accepted, the program control returns
to the main program, where sparticle decays are performed.

There are, therefore, three steps in the generator {S{\small USY23}},
the first is
the source generation, the second is the integration and the third is
the event generation.
In addition to the user interface program {\tt susy23}, the following
programs are available in the {S{\small USY23}} system:
\begin{itemize}
\item[i)] Twenty-three function programs {\tt FUNC}s for final 3-body
or 2-body SUSY processes, each of which calculates the numerical
value of the differential cross section for each process.
\item[ii)]
The kinematics subprogram {\tt KINMOQ} is called when initial state
radiation (ISR) based on QEDPS, the QED parton shower model, is
requested. Although {\tt KINEMO} covers both the case where no
ISR is produced and where at most 2 photons can be generated
at zero angle following the electron structure function method.
\item[iii)] An extended version of the {\tt CHANEL} \cite{chanel}
library
to include MSSM couplings. The {\tt CHANEL} library
calculates the numerical values of Feynman
diagrams based on the helicity amplitudes method.
\item[iv)] The numerical integration and event generation program
package {\tt BASES/SPRING v5.1} \cite{bases}.
\item[v)] The main programs, {\tt MAINBS} and {\tt MAINSP}, and
all program components for the integration and event generation steps.
\item[vi)] The subprograms for branching ratios and sparticle decays.
\item[v)] The interface programs to {\tt JETSET}
 ({\tt GR2LND}, {\tt SP2LND} and {\tt GRC2SH}).
\end{itemize}
\par\noindent
The function of these program components and relationship among them
are presented in the next three subsections.
\par

\medskip
\medskip
\medskip
\leftline{\large\bf 4.1 Source generation step}
\smallskip
The user interface program {\tt susy23} reads the parameters from
the control data file, which contains
process selection, type of radiative corrections,
SUSY parameters, etc.
The complete list of parameters is found in
Appendix B.
Then {\tt susy23} generates the following program code:

\par
\begin{itemize}
\item[i)] Three initialization subprograms {\tt USRPRM}, {\tt MODMAS}
          {\tt KINIT}, {\tt USERSP} and
\item[ii)] A "{\tt Makefile}".
\end{itemize}

\medskip
\leftline{\large\bf 4.2 Integration step}
\smallskip
\par
Before starting the numerical integration, the main program {\tt MAINBS}
invokes an initialization subprogram {\tt USERIN}, in which the
following subprograms are called in this order:
\par
\smallskip
\begin{tabular}{llp{30em}}
{\tt USRPRM} & : & To define the set of input SUSY parameters
                  and some optional parameters. \\
{\tt SETMAS} & : & To set default values to particle masses and
decay widths. \\
{\tt MODMAS} & : & To alter the default values of all parameters defined
in {\tt SETMAS}.\\
{\tt AMPARM} & : & To set the coupling constants and other
parameters.\\
{\tt KINIT}  & : & To set the parameters for the integration,
kinematics, cuts and to initialize the histogram package.
\end{tabular}
\par
The subprograms {\tt SETMAS} and {\tt AMPARM} are generated
by the {\tt GRACE} system.
By default ino and charged Higgs masses, as well as ino
mixing angles (see Sec.2.3) and all branching ratios, are calculated
in the framework of the MSSM.
Users can selectively set the values of these parameters
and some branching ratios.
Only naive consistency checks are made,
such as the normalization check of the branching ratios
and the mass ordering check,
so all modifications on these parameters or branching ratios in
the subprograms {\tt USRPRM}, {\tt MODMAS} and {\tt KINIT} are
on the users' own responsibility.
\par
The integration program {\tt BASES} calculates the scattering
cross section by sampling the function {\tt FUNC} on the allowed
phase space segmented by a self adapted grid where finer
cells are clustered on the high gradient zones. This is an
iterative procedure
running until either the maximum number of allowed iteration
is reached or the required accuracy is obtained.
In the function program {\tt FUNC},
the kinematics subroutine {\tt KINEMO}
or {\tt KINMOQ} maps the integral variables
into the four-momentum of the final state particles.
{\tt KINEMO} is called for reactions with no radiative corrections
or those
involving the initial state radiation
treated with the structure function
techniques. {\tt KINMOQ} is called for processes
in which radiative
corrections are computed with the QED parton shower method.
The subprograms {\tt AMPTBL} and {\tt AMPSUM} are further called
for calculating the helicity amplitudes and the
squared of their sum.

{\bf It is recommended to look at the integration result carefully,
especially over the convergency behaviors both
for the grid optimization and integration steps.}
When the accuracy of each iteration fluctuates from iteration to iteration
or when
it jumps up suddenly to a large value compared
to the other
iterations, the resultant estimate of the integral may not be reliable.
There are two possible origins of this behavior; too few
sampling points or/and an unsuitable choice of
the kinematical variables.

After the numerical integration by {\tt BASES},
the subprograms {\tt BSINFO}
and {\tt BHPLOT} are called to print the result of integration and
the histograms, respectively.
Before terminating the integration procedure the probability
distribution of the integrand can be saved in a file named
{\tt bases.data}
by invoking {\tt BSWRIT}, which is later used for the event generation
by {\tt SPRING}.
\par

\medskip
\medskip
\leftline{\large\bf 4.3 Event generation step}
\smallskip
\par
The main program, {\tt MAINSP}, handles
the event generation step.
The subprogram {\tt BSREAD} reads the data file {\tt bases.data}
to restore
the probability distribution and then the subprogram {\tt USERIN}
is called.
Each call to {\tt SPRING} generates one event by sampling a point
in the phase volume. It first
calculates the differential cross section at that point using
the same function {\tt FUNC} in the integration step and
returns the weight of this sampling point.
A weight one event is finally produced using usual unweighting
technique.
Subsequently, {\tt SUDCAY} handles the sparticle decay.
By calling the subprogram {\tt SP2LND},
the event information
including the color connection to be used by {\tt JETSET}
is stored in the labelled common {\tt LUJETS}.

Then hadronization of quarks and gluons can be
performed by calling {\tt LUEXEC}.
At the end of the event generation, the routine {\tt SPINFO} and
{\tt SHPLOT}
are invoked successively for printing event generation information and
histograms.

\section{How to run the program} \label{run}
\leftline{\large\bf 5. How to run the program}

The user should first prepare the control data to define the process,
the option flags, the MSSM parameters and the experimental cuts.
The user interface program {\tt susy23} takes this control data
as an input. For example, let's call the following sequence of lines
{\tt control.data}.
\par\smallskip
{\tt
\begin{tabular}{lll}
process & = & SW1sw1 \\
energy  & = & 200.0d0 \\
type    & = & tree \\
hadron  & = & no \\
tanbe  & = & -2.0d0 \\
xm2  & = & 50.0d0 \\
xmu  & = & 150.0d0 \\
end & &
\end{tabular}
}
\par\smallskip\noindent
The first line specifies the process to be calculated and
the second is the center of mass energy in GeV unit.
The others are options,
whose meanings are given in Appendix B.
Then the user may type:
\par
\begin{verbatim}
\end{verbatim}
\par\noindent
If the message ``syntax error'' is returned,
the user must carefully examine the contents of the control data.
No file is generated in this case.
When the control data is accepted
the following message appears:
\par
\begin{verbatim}
Process is "SW1sw1"
Energy is "200.0d0"
HADRNZ <no>
bye-bye
directory name is SW1sw1
absolute directory name is /home/susy23/prc/SW1sw1
------------------------------------------
cd /home/susy23/prc/SW1sw1
make integ
integ
make spring
spring
------------------------------------------
\end{verbatim}
\par\noindent
According to the parameters given in the control data,
the files, i.e.~ {\tt usrprm.f},
{\tt modmas.f}, {\tt kinit.f},
{\tt usersp.f} and {\tt Makefile}, are generated in
a specified subdirectory ( {\tt SW1sw1} in this case).
\par\noindent
According to the last five lines in the message,
users can proceed with the calculations as follows:
\par
\begin{itemize}
\item[i)] Change directory by typing:
\begin{verbatim}
\end{verbatim}
\item[ii)] Create an executable {\tt integ} for the integration by typing:
\begin{verbatim}
\end{verbatim}
\par
\item[iii)] Numerical integration is actually performed by typing:
\begin{verbatim}
\end{verbatim}
\par
The results of
integration step are displayed on the console as well as written in an
output file
{\tt bases.result}. The total cross section in $pb$ and the
estimated statistical error are shown
on the last line, under {\tt Cumulative Result},
in the table of the {\tt Convergence Behavior for the Integration step}.
The differential cross sections are also printed as a function of the energy,
scattering angle of each particle and invariant masses of any two final particles.
The probability distribution of the integrand is written in a file
{\tt bases.data} which will be used in the event generation step by {\tt spring}.

\item[iv)] Before running the event generation, users may edit
{\tt mainsp.f} to set additional parameters if needed
and call user's own analysis routines.

The following is the structure of the generated {\tt mainsp.f}, where
four-momentum of all particles are stored in the {\tt common/lujets/} in the
{\tt JETSET} format when subprogram {\tt sp2lnd} is called in the event-loop:
\begin{verbatim}
      Program  mainsp
      implicit real*8(a-h,o-z)
      external func
       ....................
      real*4  p,v
      common/lujets/n,k(4000,5),p(4000,5),v(4000,5)
       ....................
       ....................
      mxtry  =   50
      mxevnt = 1000
      do 100 nevnt = 1, mxevnt

         call spring( func, mxtry )
       ....................
*         -----------------
           call sp2lnd
*         -----------------
*
*       ==============================================
*       (  user_analysis based on the common lujets )
*       ==============================================
*
  100 continue
       ....................
      stop
      end
\end{verbatim}

\item[v)] Create an executable {\tt spring} for event generation
by typing:

\begin{verbatim}
\end{verbatim}

\item[vi)] Start the event generation by typing:

\begin{verbatim}
\end{verbatim}

Information on the event generation will be written in the
{\tt spring.result} file. Users should pay attention to the
histograms generated in this step.
The distributions of the generated events are superimposed
with the character ``{\tt 0}'' on the histograms generated in
the integration step. These two
distributions should be consistent with each other
within the statistical error of
the generation. For the detail of the output files of {\tt BASES}
and {\tt SPRING},
users can consult the Ref.\cite{bases}.
\end{itemize}

\section{Conclusion and remarks} \label{remarks}

The {S{\small USY23}} system calculates the effective cross
section and generates events for one of
the twenty-three SUSY processes
at $e^+e^-$
colliders listed in Appendix C.
It is dedicated to the LEP2 studies.
The numbers 2 and 3 in S{\small USY23} refer to the fact that
processes with 2 and also 3 final particles are fully computed at
tree level in the massive case.
These particles are then allowed to decay producing
multi-particle final states.
Sparticle widths and decay branching ratios
in accordance with this energy range
are calculated.
In particular, the helicity information for
direct decays of spinor sparticles (the lighter chargino and
the second lightest neutralino) is handled properly.
The produced
quarks can be hadronized according to {\tt JETSET}.
Processes with initial radiations can be
generated in terms of the electron structure function or the QED
parton shower method.
