Description

The neutrino mass models containing different scalars are constructed using $A_{4}\times Z_{4}$ discrete symmetry group. The mass matrices are developed in such a way that they can give necessary deviation from Tribimaximal mixing to generate non-zero $\theta_ {13}$. The resultant mass matrices are analyzed and compared to understand the contribution of $A_{4}$ singlet scalars to the mass model. In addition, we also try to find the minimal number of scalar fields necessary to construct a neutrino mass model that can reproduce the current oscillation data with good accuracy.
