-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.+Collider physics needs cross sections for a great number of various reactions.
