Abstract

In a supersymmetric scenario, we study masses and mixings for leptons through the \bf Q₆ flavour symmetry. In the simplest case, the \bf M_ν effective neutrino mass matrix, that comes from the type I see-saw mechanism, breaks the μ↔ τ interchange symmetry. As consequence, the reactor and atmospheric angles deviate from 0^∘ and 45^∘, respectively. At first glance, the model might accommodate very well the reactor and atmospheric angles in good agreement with the experimental data.
