Reproducing lepton mixing in a texture zero model

High Energy Physics - Phenomenology 2015-06-16 v1

Abstract

We note that the emerging features of lepton mixing can be reproduced if, with inverted neutrino mass ordering, both the smallest neutrino mass and the ττ\tau\tau element of the neutrino mass matrix vanish. Then, the atmospheric neutrino mixing angle is less than maximal and the Dirac phase δ\delta is close to π\pi. We derive the correlations among the mixing parameters and show that there is a large cancellation in the effective mass responsible for neutrinoless ββ\beta\beta decay. Three simple seesaw models leading to our scenario are provided.
