Photon mass and electrogenesis
Alexander Dolgov, Diego N. Pelliccia
Abstract
We show that if photon possesses a tiny but non-vanishing mass the universe cannot be electrically neutral. Cosmological electric asymmetry could be generated either at an early stage by different evaporation rates of primordial black holes with respect to positively and negatively charged particles or by predominant capture of protons in comparison to electrons by heavy galactic black holes in contemporary universe. An impact of this phenomenon on the generation of large scale magnetic fields and on the universe acceleration is considered.
