Poster contribution

Discrete symmetries are being preferred to explain the neutrino phenomenology, we chose the simplest $S_3$ group and explore the implication of its modular form on neutrino masses and mixing. Non-trivial transformations of Yukawa couplings under this symmetry, make the model phenomenologically interesting by reducing the requirement of multiple scalar fields. This symmetry imposes a specific...

Poster contribution

In this work, a flavour theory, of a neutrino mass model implementing an $A_4$ family symmetry is proposed. This scheme provides a simple way to derive tribimaximal mixing in the neutrino sector via spontaneous breaking of $A_4 $ symmetric model leading to acceptable values of $\theta_{13}$ and maximal CP violation. A $z_2 \times z_2$ invariant perturbations in this model is introduced in the...
