# FeynGrav: FeynCalc extension for gravity amplitudes

@article{Latosh2022FeynGravFE, title={FeynGrav: FeynCalc extension for gravity amplitudes}, author={Boris Latosh}, journal={Classical and Quantum Gravity}, year={2022}, volume={39} }

Package ‘FeynGrav’ which provides a framework to operate with Feynman rules for gravity within ‘FeynCalc’ is presented. We present a framework to deal with Feynman rules for general relativity and non-supersymmetric matter minimally coupled to gravity. Applicability of the package is tested with 2 → 2 on-shell tree level graviton scattering, polarization operators, and one-loop scalar-gravitational interaction structure.
