Natural mass hierarchy among three heavy Majorana neutrinos for resonant leptogenesis under modular A 4 symmetry
Abstract It is clear that matter is dominant in the Universe compared to antimatter. We call this problem baryon asymmetry. The baryon asymmetry is experimentally determined by both cosmic microwave background and big bang nucleosynthesis measurements. To resolve the baryon number asymmetry of the U...
