Dilution of baryon asymmetry in the early universe due to primordial
  blackhole decay
  Primordial black holes which are created at the very early universe can get
decayed in the matter dominated era and thus produce photons, hence resulting
in dilution of the baryon asymmetry and evolution of the cosmological scale
factor. This process is tested and calculated by considering instant decay
approximation, the realistic model of universe expansion and also considering
the LogNormal spectrum of the primordial blackholes.
