Superluminal Velocity of Photons in a Gravitational Background

Abstract

The influence of radiative corrections on the photon propagation in a gravitational background is investigated without the low-frequency approximation $\omega \ll m$. The conclusion is made in this way that the velocity of light can exceed unity.
