Matter-antimatter asymmetry in minimal inverse seesaw framework with A 4 modular symmetry

Abstract We propose a minimal inverse seesaw framework based on A 4 modular symmetry. We have studied the neutrino oscillation parameters in our work and our model excludes some 3 σ values of the mixing angle θ 23 . Also, there is a clear linear relation between the mixing angles θ 12 and θ 23 found in the allowed 3 σ region. We also examine whether the parameter points consistent with neutrino oscillation data simultaneously comply with the experimental limits on lepton flavor violating (LFV) decays, specifically: μ ⟶ eγ , τ ⟶ eγ , and τ ⟶ μγ . We have also investigated the matter-antimatter asymmetry of our universe via the resonant leptogenesis mechanism. Here, we present the contribution of lepton number conserving scattering processes mediated by the Z ′ boson in the context of leptogenesis.
