| contents | In this work we have realized texture zero structures of neutrino mass matrix through our study of neutrino phenomenology and dark matter. For analysing these processes, we have constructed a model in minimal inverse seesaw, ISS(2,3) by using $A_4$ discrete symmetry. The particle content of ISS(2.3) has been augmented by a scalar triplet $η=(η_1,η_2,η_3)$. The probable dark matter candidates for this model are the neutral components of $η$. The three mass matices of ISS(2,3), $M_D$, $M_{NS}$ and $M_S$ contribute to the structure of light neutrino mass matrix $m_ν$. Here we try to examine the impact on texture structures of $m_ν$ due to different possible 2-0 structures of $M_D$. To examine further possible contraints, we have evaluated the neutrino parameters and calculated relic density of dark matter for the favourable cases. From our analysis we find that out of the fifteen possible 2-0 structures, only two of them ($M_{D3}$ and $M_{D6}$) successfully generates all the mixing angles in the allowed ranges. |
