O’Mega: An optimizing matrix element generator

By Thorsten Ohl. 2000

342 citations recorded by the source corpus.

I sketch the architecture of O’Mega, a new optimizing compiler for tree amplitudes in quantum field theory. O’Mega generates the most efficient code currently available for scattering amplitudes for many polarized particles in the standard model. A complete infrastructure for physics beyond the standard model is provided.
