Electrogenesis via primordial black holes

It was recently shown that the vanishing of the Coulomb field related to the electric charge of a black hole by virtue of a tiny but non-vanishing photon mass can produce an electric asymmetry in the universe. This process can have place both at a cosmological early stage, through primordial black holes, and in contemporary universe, by means of supermassive black holes at galactic centers. Possible consequences of the latter case about the role of electrogenesis in the generation of magnetic fields coherent on galactic scale have been investigated. In this paper we will discuss the electrogenesis mediated by primordial black holes and analyze different realizations of the mechanism in this case.
