Correlations between low energy leptonic CP violation and leptogenesis in the light of recent experiments

Abstract

Leptogenesis is the most favourable mechanism for generating the observed baryon asymmetry of the Universe (BAU) which implies CP violation in the high energy scale. The low energy leptonic CP violation is expected to be observed in the neutrino oscillations and $0\nu 2\beta$ decay experiments. Generally it is not possible to connect both the CP violations. Here we revisit the issue of connecting the two in flavoured leptogenesis scenario within the Type I seesaw in the light of recent neutrino oscillation and {\it Planck} data. With the recent precise measurements of ${\theta }_{13}$ and BAU we are able to find new correlations between the low and high energy CP violating phases when leptogenesis occurs at temperature between $10^9$ to $10^{12}$ GeV and there is no contribution to CP violation from the heavy neutrino sector.
