چکیده

PSGen is a new general purpose Fortran program which has been written to facilitate the Monte Carlo phase space integration of S matrix element any 2→n scattering process, with n=2,...,9, provided by user. The in 90/95. It uses very fast algorithm that automatically generates calls subroutines containing different parameterizations considered class processes. take into account mappings poles due Feynman propagators unstable heavy particles decaying 2 or 3 on shell final state according predefined patterns, possible single double t-channel and peaks one photon gluon radiation. individual are organized multichannel kinematics subroutine can be easily called while computing integral as function generated particle four momenta, either leading higher orders perturbation series. momenta used quadruple precision version, if necessary.

Monte-Carlo and Quasi-Monte-Carlo Methods for Numerical Integration

We consider the problem of numerical integration in dimension s, with eventually large s; the usual rules need a very huge number of nodes with increasing dimension to obtain some accuracy, say an error bound less than 10−2; this phenomenon is called ”the curse of dimensionality”; to overcome it, two kind of methods have been developped: the so-called Monte-Carlo and Quasi-Monte-Carlo methods. ...

PHASE , a Monte Carlo event generator for six - fermion physics at the LHC . ∗

PHASE is a new event generator dedicated to the study of Standard Model processes with six fermions in the final state at the LHC. The code is intended for analyses of vector boson scattering, Higgs search, three gauge boson production, and top physics. This first version of the program describes final states characterized by the presence of one neutrino, pp → 4q + lνl, at O(α6). PHASE is based...
