摘要: The program MadGraph is presented which automatically generates postscript Feynman diagrams and Fortran code to calculate arbitrary tree level helicity amplitudes by calling HELAS[1] subroutines. written in available Unix VMS versions. currently includes standard model interactions of QCD QFD, but easily modified include additional models such as supersymmetry.
