Abstract

An attempt was made to show how CP violation responsible for baryogenesis manifests itself in the MNS matrix and the Jarlskog determinant which signals low energy CP violation in neutrino oscillation. Furthermore, it was demonstrated that it is possible to estimate the size and sign of the baryon number in the most general case once |(U_MNS)_e3| neutrinoless double beta decay and CP violation of neutrino oscillation are measured. A correlation between CP violation in neutrino oscillation and leptogenesis was studied and the size of neutrino CP violation (J) was estimated.
