AN ELECTROWEAK MONTE-CARLO FOR 4-FERMION PRODUCTION

An electroweak event generator for the four-fermion production process e+e- --> ffFFBAR is described. This generator, FERMISV, includes all the lowest-order diagrams involving Z and photon propagators. It uses multichannel phase space methods to map the very many peaks of the differential cross section. A leading-log approach to initial- and final-state radiation has been included to make FERMISV useful for phenomenology in the range 20 GeV < square-root s < 200 GeV, where square-root s is the center-of-mass energy of the initial beam particles. The methodology employed to write this generator allows facile adaptation and generalization.
