Description

We show that seesaw models based on flavor symmetries (such as A4 and Z7 x Z3) which produce exact tribimaximal neutrino mixing also imply a vanishing leptogenesis asymmetry. We show that higher order symmetry breaking corrections in these models can give a non-zero leptogenesis asymmetry and generically also give deviations from tribimaximal mixing and a non-zero θ13≥10-2
