# FeynRules 2.0 — A complete toolbox for tree-level phenomenology

## Description

Abstract FeynRules is a Mathematica-based package which addresses the implementation of particle physics models, which are given in the form of a list of fields, parameters and a Lagrangian, into high-energy physics tools. It calculates the underlying Feynman rules and outputs them to a form appropriate for various programs such as CalcHep, FeynArts, MadGraph, Sherpa and Whizard. Since the original version, many new features have been added: support for two-component fermions, spin-3/2 and spin-2 fi... Title of program: FeynRules 2.0 Catalogue Id: AEDI_v2_0 Nature of problem The program computes the Feynman rules of any quantum field theory, expressed in four-dimensional spacetime, directly from the Lagrangian of the model. Various interfaces to Feynman diagram calculators are included that allow the exportation of the interaction vertices in a format readable by different Monte Carlo event generators or symbolic calculation tools.
