 Title: “Inverse See-Saw Mechanism with S3 Flavor Symmetry”

Abstract:

Cobimaximal mixing predicts π/4 and 3π/2 for the atmospheric angle and the Dirac CP-violating phase, respectively. These values are in tension with the neutrino globals fits. If this pattern was behind the lepton mixings, then it would have to be broken. In my presentation, I discuss the S3 flavor symmetry within the B− L gauge model where the Cobimaximal pattern comes from the neutrino sector but the charged lepton contribution breaks the well known predictions so the mixing observables can be accommodated quite well according to the available data. In addition to this, some phenomenological aspects as neutrinoless double beta decay and lepton decays will be commented.
