In search of Dirac neutrino masses through baryogenesis in normal hierarchy

Theoretical Physics


We point out a possible way to settle the issue of the Dirac neutrino mass hierarchy. Constraining the observed baryon asymmetry to the normal hierarchy mass model within the seesaw framework, we look for the possible structure of coveted Dirac neutrino masses. We have found the possible structure of the Dirac neutrino masses to be (λ72,1)v in terms of the parameter λ=0.3, with v as an overall scale factor.
