Wwgenpv − a Monte Carlo Event Generator for Four-fermion Production in E
نویسندگان
چکیده
The Monte Carlo program WWGENPV, designed for computing distributions and generating events for the four-fermion process ee → WW → 4f , is described. It is based on the calculation of the exact tree-level matrix element of the four-fermion reaction and includes initial-state radiation in the leading-log approximation within the structure function approach. The program can be used in a two-fold way: as a Monte Carlo integrator for weighted events, providing predictions for the total cross section, the W invariant-mass distribution, the radiative energy and invariant-mass loss; as a true event generator of unweighted events, useful for simulation purposes.

ERATO is a Monte Carlo event generator describing four fermion production at LEP2 and beyond. All tree-order processes leading to four fermions are included, taking into account all relevant QCD contributions. QED higher order corrections are introduced via a structure function approach, whereas weak corrections related to fermion loops are also included. Special attention has been paid in stud...

The implementation of QED initial-state radiative corrections in the process of four-fermion production at LEP200 and higher-energy e+e− colliders is discussed. Because of the presence of charged-current processes, this is a nontrivial problem, and we compare our approach with other existing treatments. We describe the Monte Carlo algorithm used for the generation of 4fermion events with photon...

The production of an intermediate-mass Higgs boson in processes of the kind e+e− → 6 fermions at the energies of future linear colliders is studied. The recently developed and fully automatic algorithm/code ALPHA is used to compute the tree-level scattering amplitudes for the reactions e+e− → μμτν̄τud̄, μμeν̄eud̄. The code has been interfaced with the Monte Carlo program HIGGSPV/WWGENPV, properly a...

The class of six-fermion production processes at ee colliders comprises very interesting particle reactions, such as the production of top-quark pairs and of Higgs bosons in the intermediate Higgs mass range, the scattering of massive gauge bosons, and triple gauge-boson production. The Monte Carlo event generator Lusifer is designed for the analysis of such processes. A few illustrating result...
