Title: On mu-tau Symmetry in Neutrino Mass Matrix
Speaker: Dr. Nidal CHAMOUN (University of Damascus, SYRIA)

Abstract: I will briefly review the mu-tau symmetry in neutrino mass matrix leading to vanishing theta_{13}. One resorts usually to perturbations in order to justify the non vanishing value of theta_{13}, and I will investigate the corresponding partial mu-tau symmetry, how it can accommodate the neutrino data, and implement it, within type-I seesaw scenario, into the lepton sector in order to generate lepton asymmetry. I will present also a realization of the high scale perturbed texture which keeps its form through seesaw into the low scale. Finally, I state a new `rotated' mu-tau symmetry leading directly, without perturbation, to non vanishing theta_{13}, and equally investigate it.
