For instance, if black holes evaporate before the thermal leptogenesis, the impact would be minimal', 'If, on the other hand, the evaporation occurs way after the thermal leptogenesis era, the outcome would depend on the right-handed neutrino masses. For large masses (&gt; 10^9 GeV) the evaporation could enhance the asymmetry.', 'but if RH neutrinos are lighter, the black hole contribution would not be sufficient, and the effect would be the contrary: BHs would diminish the lepton asymmetry because of the extra radiation produced.', ""So, we find that for the intermediate scale leptogenesis, BHs always tend to decrease the asymmetry, even for very fine tunned scenarios! Then, if it's proven that the Universe had a BH dominated era, this could put tension on this leptogenesis case."", ""This was a fun project! I'm looking forward to understanding the effects of BHs in other leptogenesis scenarios!"", '@tabrizi_zahra Not so many 😀']",20,10,1275
