  Studies Beyond the Standard Model (BSM) will become more and more important
in the near future with a rapidly increasing amount of data from different
experiments around the world. The full study of BSM models is in general an
extremely time-consuming task involving long and difficult calculations. It is
in practice not possible to do exhaustive predictions in these models by hand,
in particular if one wants to perform a statistical comparison with data and
the SM. Here we present MARTY (Modern ARtificial Theoretical phYsicist), a new
C++ framework that fully automates calculations from the Lagrangian to physical
quantities such as amplitudes or cross-sections. This framework can fully
simplify, automatically and symbolically, physical quantities in a very large
variety of models. MARTY can also compute Wilson coefficients in effective
theories. This will considerably facilitate the study of BSM models in flavor
physics. Contrary to the existing public codes in this field MARTY aims to give
a unique, free, open-source, powerful and user-friendly tool for high-energy
physicists studying predictive BSM models, in effective or full theories up to
the 1-loop level, which does not rely on any external package. With a few lines
of code one can gather final expressions that may be evaluated numerically for
statistical analysis. Features like automatic generation and manual edition of
Feynman diagrams, comprehensive manual and documentation, clear and easy to
handle user interface are amongst notable features of MARTY.
