Complex Scaling in Neutrino Mass Matrix

High Energy Physics - Phenomenology 2016-04-06 v1

Abstract

Using the residual symmetry approach, we propose a complex extension of the scaling ansatz on MνM_\nu which allows a nonzero mass for each of the three light neutrinos as well as a nonvanishing θ13\theta_{13}. Leptonic Dirac CP violation must be maximal while atmospheric neutrino mixing need not to be exactly maximal. Each of the two Majorana phases, to be probed by the search for 0νββ0\nu \beta\beta decay, has to be zero or π\pi and a normal neutrino mass hierarchy is allowed.
