FeynGrav 2.0
arXiv:2302.14310 · doi:10.1016/j.cpc.2023.108871
Abstract
We present a new version of FeynGrav. The present version supports Feynman rules for matter with non-vanishing mass and Yang-Mills model. We revisit the gauge fixing procedure for gravity and derive interaction rules valid for an arbitrary gauge fixing parameter. We provide a few simple examples of calculations to illustrate package usage.
