Active and sterile neutrino phenomenology with A4 based minimal extended seesaw
Speaker: Pritam Das (Department of Physics, Tezpur University, Assam)
Date and Time: 13/08/2019, 3:00 p.m.
Venue: LH-3
Abstract:
We study a model of neutrino within the framework of minimal extended seesaw (MES), which plays an important role in active and sterile neutrino phenomenology in (3+1) scheme. The A4 flavor symmetry is augmented by additional Z4×Z3 symmetry to constraint the Yukawa Lagrangian of the model. We use non-trivial Dirac mass matrix, with broken μ−τ symmetry, as the origin of leptonic mixing. Interestingly, such structure of mixing naturally leads to the non-zero reactor mixing angle θ13. Considering non-degenerate mass structure for right-handed neutrinos , we have also shown three different cases for sterile neutrino mass, to check the viability of this model, within the allowed 3σ bound in this MES framework.
