New Features in FormCalc 4

Abstract

FormCalc is a Mathematica package for the automatic computation of tree-level and one-loop Feynman amplitudes. It accepts diagrams generated by FeynArts, simplifies them, and generates a complete Fortran code for their numerical evaluation. Version 4 includes new features which enhance performance, convenience of use, and modularity/code reusability.Comment: 5 pages, Talk given at the 7th DESY Workshop On Elementary Particle Theory: Loops And Legs In Quantum Field Theory, Zinnowitz, Germany, 25-30 Apr 200
