O'Mega

O’Mega: An Optimizing Matrix Element Generator 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.
