This analysis demonstrates neutrino behavior and dark matter relationships, suggesting two successful structures. The study uses a minimal inverse seesaw model augmented by discrete symmetry.
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 A₄ discrete symmetry. The particle content of ISS(2.3) has been augmented by a scalar triplet η=(η₁,η₂,η₃). The probable dark matter candidates for this model are the neutral components of η. The three mass matices of ISS(2,3), MD, MNS and MS 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 MD. 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 (MD3 and MD6) successfully generates all the mixing angles in the allowed ranges.
