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.
