Description

Abstract WPHACT 2.0 is the new fully massive version of a MC program and unweighted event generator which computes all Standard Model processes with four fermions in the final state at e^+e^-colliders. The program can now generate unweighted events for any subset of all four fermion final states in a single run, by making use of dedicated pre-samples which can cover the entire phase space. Improvements with respect to WPHACT 1.0 include the Imaginary Fermion Loop gauge restoring scheme, new phase ... Title of program: WPHACT, version 2.0 Catalogue Id: ADEN_v2_0 [ADQW] Nature of problem All e+e- Standard Model (SM) processes with four fermion final states are necessary for detailed studies of the properties of the W and of the Higgs bosons, for measuring double and single boson production, for high precision tests of the SM and for evaluating backgrounds to searches. One wants therefore a Monte Carlo event generator which provides an accurate description of all four fermion processes in the largest possible region of phase space and which can be used for realistic experimental ...
