== A Mathematica package to calculate Feynman rules ==

!FeynRules is a Mathematica® package that allows the calculation of Feynman rules in momentum space for ''any'' QFT physics model. The user needs to provide !FeynRules with the minimal information required to describe the new model, contained in the so-called model-file. This information is then used to calculate the set of Feynman rules associated with the Lagrangian. The Feynman rules calculated by the code can then be used to implement the new physics model into other existing tools, such as MC generators. This is done via a set of interfaces which are developed together and maintained by the corresponding MC authors.
