Description
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
computations. 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. Some Mathematica
packages can perform this kind of computations automatically. However we
are some times interested in a different formulation of a given theory,
a low energy effective theory. In this case, one must compute Wilson
coefficients instead of amplitudes. This is the case in flavor physics,
the study of flavor-changing quark currents which concentrates many
hopes of new physics discovery, where physical observables are fully
expressed in terms of an effective theory.
Here we present CSL (C++ Symbolic computation Library) together with
CSL-HEP (CSL extended for High Energy Physics), a new C++ framework that
fully automates computations from the lagrangian to physical quantities
such that amplitudes or cross-sections. This framework can fully
simplify, automatically and symbolically, physical quantities in a very
large variety of models. CSL-HEP can also compute Wilson coefficients
for arbitrary operators in an effective theory. This will considerably
facilitate the study of BSM models in flavor physics.
CSL-HEP 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 order. With a
few lines of code and in very little time (less than a second to a few
seconds for one process) one can gather final expressions that may be
evaluated numerically for statistical analysis. Features like automatic
generation and manual edition of Feynman diagrams, exhaustive and
comprehensive manual and documentation, clear and easy to handle user
interface, will make the life of users easier.
