Abstract WPHACT (W W and Higgs Physics with PHACT) is a MC program and unweighted event generator which computes all Standard Model processes with four fermions in the final state at e^+ e^-colliders. It is based on an helicity amplitude method which allows precise and fast evaluations of the matrix elements both for massless and massive fermions. Fermion masses for b quarks are exactly taken into account. QED initial state and Coulomb corrections are evaluated, while QCD final state corrections are... Title of program: WPHACT Catalogue Id: ADEN_v1_0 Nature of problem The forthcoming experiments at the high energy electron-positron collider LEP2 will be mainly concerned with WW physics and Higgs search. The production of two W's will allow the direct study of the triple- boson coupling and a precise measurement of the mass of the W. The search for the Higgs is of primary importance for understanding the problem of mass generation in the Standard Model (SM). Small deviations from the SM will be important for discovering possible new physics. Both WW and Higgs ...
