O'Mega: An Optimizing Matrix Element Generator Thorsten Ohl1, Jürgen Reuter2, Christian Schwinn3 Wuerzburg University & Karlsruhe University IKDA 2001/06-rev LC-TOOL-2001-040-rev hep-ph/0102195-rev

Abstract: We sketch the architecture of O'Mega, a new optimizing compiler for tree amplitudes in quantum field theory, and briefly describe its usage. O'Mega generates the most efficient code currently available for scattering amplitudes for many polarized particles in the Standard Model and its extensions.
