MadGraph is a very powerful software framework that aims at providing all the elements necessary for SM and BSM phenomenology, such as the computations of cross sections, the generation of hard events and their matching with event generators, and the use of a variety of tools relevant to event manipulation and analysis. It can be downloaded at
We have prepared a
short introduction
to the
usage of MadGraph in simple
problems of calculationg cross sections. We chose the simple example
of
that we have discussed
before. After getting acquainted with this usage you should go to the
web page
and look
at the tutorials.
