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. 

FeynMG: a FeynRules extension for scalar-tensor theories of gravity

The ability to represent perturbative expansions of interacting quantum field theories in terms of simple diagrammatic rules has revolutionized calculations in particle physics (and elsewhere).

Scalaron Decay in Perturbative Quantum Gravity

A certain quadratic gravity model provides a successfully inflationary scenario. The inflation is driven by the new scalar degree of freedom called scalaron. After the end of inflation the scalaron



Gravity-Matter Feynman Rules for any Valence

This article derives and presents the Feynman rules for (effective) quantum general relativity coupled to the standard model for any vertex valence and with general gauge parameter ζ. The results are

Non-minimal interactions are proven to be generated at the one-loop level in simple scalar-tensor gravity models. The John interaction from the Fab Four class is generated. The interaction affects

One loop divergencies in the theory of gravitation

All one-loop divergencies of pure gravity and all those of gravitation interacting with a scalar particle are calculated. In the case of pure gravity, no physically relevant divergencies remain;

Quantum gravitational corrections to the nonrelativistic scattering potential of two masses

We treat general relativity as an effective field theory, obtaining the full nonanalytic component of the scattering matrix potential to one-loop order. The lowest order vertex rules for the

Algorithm for Computing the Propagator for Higher Derivative Gravity Theories

A simple algorithm for computing the propagator for higher derivative gravitytheories based on the Barnes–Rivers operators is presented. The prescription isused, among other things, to obtain the

Graviton Physics

The interactions of gravitons with matter are calculated in parallel with the familiar photon case. It is shown that graviton scattering amplitudes can be factorized into a product of familiar
