We discuss how CP violation generating lepton number asymmetry can be related to CP violation in low energy.
As is well-known, there exist totally three CP-violating phases in the leptonic sector if three ordinary neutrinos are massive Majorana particles. In this short note, we raise the question whether the number of sufficient and necessary…
