This ensures that our calculation incorporates the best possible value for the W branching ratio which is determined to about 1%. The values of the total Higgs width are taken from the program hdecay [27], version 3.51. 

To define the jets we perform clustering according to the k$_{T}$ algorithm [28], with jet definitions detailed further below. 

## IV. TEVATRON RESULTS 

We use a very simple set of inclusive cuts, with no requirements on the Higgs boson decay products,

At the Tevatron the search for the Higgs boson has been divided into jet bins. To set the stage for this we show in Table I the expected cross section in each bin due to the gluon fusion mechanism. The parameter µ is the renormalization and factorization scale, which we set equal to m$_{H}$ here. We note that next-to-next-to-leading order (NNLO) results for the Higgs + 0 jet cross section are given in [29], based on the earlier calculations in Refs. [30–32]. From table I columns 3 and 5, we see that the Higgs + ≥ 2 jets bin constitutes about 13% of the cross section for | η$_{jet}$ | < 2 . 5 and 11% with | η$_{jet}$ | < 2. 

It is interesting to compare the number for the fraction of Higgs + ≥ 2 jet events ( | η$_{jet}$ | <
