Résumé

Motivated by the recent results from Daya Bay, Reno and Double Chooz Collaborations, we study the consequences of small departures from exact μ − τ symmetry in the neutrino sector, to accommodate a nonvanishing value of the element Ve3 from the leptonic mixing matrix. Within the seesaw framework, we identify simple patterns of Dirac mass matrices that lead to approximate μ − τ symmetric neutrino mass matrices, which are consistent with the neutrino oscillation data and lead to nonvanishing mixing angle Ve3 as well as precise predictions for the CP-violating phases. We also show that there is a transparent link between neutrino mixing angles and seesaw parameters, which we further explore within the context of leptogenesis as well as double beta decay phenomenology.
