Query: Active and sterile neutrino phenomenology with $A_4$ based minimal
  extended seesaw   We study a model of neutrino within the framework of the minimal extended
seesaw (MES), which plays an important role in active and sterile neutrino
phenomenology in (3+1) scheme. The $A_4$ flavor symmetry is augmented by an
additional $Z_4\times Z_3$ symmetry to constraint the Yukawa Lagrangian of the
model. We use non-trivial Dirac mass matrix, with broken $\mu-\tau$ symmetry,
as the origin of leptonic mixing. Interestingly, such a structure of mixing
naturally leads to the non-zero reactor mixing angle $\theta_{13}$.
Non-degenerate mass structure for right-handed neutrino $M_R$ is considered so
that we can further extend our study to Leptogenesis. We have also considered
three different cases for sterile neutrino mass, $M_S$ to check the viability
of this model, within the allowed $3\sigma$ bound in this MES framework.
