Photon Mass in Inflation and Nearly Minimal Magnetogenesis
Abstract
We argue that the dynamics of photons canonically coupled to scalars in de Sitter inflation gets modified by a photon mass term. This might have lead to generation of potentially observable magnetic field correlated over cosmological scales today.
