Automatic generation of tree level helicity amplitudes
Listed in Teesside University Research Data Repository
Description
Abstract
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. The program is written in Fortran and is available in Unix and VMS versions. MadGraph currently includes standard model interactions of QCD and QFD, but is easily modified to include additional models such as supersymmetry.

Title of program: MadGraph Catalogue Id: ACTX_v1_0 Nature of problem Calculation of higher order tree level Feynman helicity amplitudes which involve several external particles can require the evaluation of hundreds of Feynman diagrams. Hand coding programs to compute these amplitudes is very time consuming and error-prone. For complex problems the widely used packages based on symbolic mathematics systems either produce inefficient code or fail because of excessive memory or CPU requirements.
