Graviton-photon conversion on spin 0 and 1/2 particles

TL;DR

This paper calculates the scattering cross-sections for graviton-photon conversion on spin 0 and 1/2 particles within linearized quantum gravity, revealing forward-peaked distributions and small magnitudes at high energies.

Contribution

It provides the first detailed calculation of graviton-photon conversion cross-sections for both bosons and fermions in linearized quantum gravity.

Findings

Cross-sections are strongly forward-peaked.

Cross-sections become constant at high energies.

Magnitudes of cross-sections are very small.

Abstract

The differential cross-sections for scattering of gravitons into photons on bosons and fermions are calculated in linearized quantum gravity. They are found to be strongly peaked in the forward direction and become constant at high energies. Numerically, they are very small as expected for such gravitational interactions.
