CompHEP: a package for evaluation of Feynman diagrams, integration over multi-particle phase space and event generation (supported in part by RFBR grants 96-02-19773-а, 99-02-04011-ННИО_а, 01-02-16710-а, 04-02-17448-а).

At present time when a new generation of TeV energy colliders is beginning to operate one needs to calculate cross sections for a great number of various reactions. The CompHEP package was created for calculation of multiparticle final states in collision and decay processes. The main idea in CompHEP was to enable one to go directly from the Lagrangian to the cross sections and distributions effectively, with the high level of automation.
While ortodox event generators are software libraries (see Event generator) of various matrix elements, CompHEP starts from the level of Feynman rules for a gauge model Lagrangian and calculates symbolically the matrix element for any process defined by a user. In this sense CompHEP is a “generator of generators” (or, following the abovementioned reference, a “meta-generator”). The Feynman rules for a gauge model Lagrangian in the format of CompHEP model files can be generated by LanHEP.
