grc4f v1.1: a four-fermion event generator for e+e− collisions

Abstract grc4f is a Monte Carlo package for generating e^+ e^-→ 4-fermion processes in the standard model. All of the 76 LEP-2 allowed fermionic final state processes evaluated at tree level are included in version 1.1. grc4f addresses event simulation requirements at e^+ e^-colliders such as LEP and upcoming linear colliders. Most of the attractive aspects of grc4f come from its link to the GRACE system: a Feynman diagram automatic computation system. The GRACE system has been used to produce the...
