Higher-Dimensional Origin of Heavy Sneutrino Domination and Low-Scale Leptogenesis
If the expectation value of the right-handed (rhd) sneutrino comes to dominate the universe, its decay naturally leads to successful leptogenesis, as well as significant dilution of dangerous inflationary relics, such as the gravitino. The resulting baryon asymmetry is independent of other cosmologi...
