Deviations to Tri-Bi-Maximal mixing in the limit of $\mu -\tau$ symmetry

Diana C. Rivera-Agudelo, S. L. Tostado, Abdel Pérez-Lorenzana

In the limit of an approximate $\mu -\tau$ symmetry in the neutrino mass matrix, we explore deviations to the Tri-Bi-Maximal mixing pattern in the neutrino sector. We consider two differ…
