New Developments in FormCalc 4.1

Abstract

FormCalc is a matrix-element generator that turns FeynArts amplitudes up to one loop into a Fortran code for computing the squared matrix element. The generated code can be run with FormCalc's own driver programs or used with other `frontends', e.g. Monte Carlos. Major new or enhanced features in Version 4.1 are: treatment of external fermions, phase-space integration, code-generation functions, extensions for the MSSM, the HadCalc frontend.
