Non-Holomorphic Modular ${\mathcal{A}}_4$ Symmetric Scotogenic Model

Abstract

The present work extends scotogenic and its modular ${\mathcal{A}}_4$ variation a step forward and demonstrates scotogenic modular ${\mathcal{A}}_4$ non-supersymmetric realization. To achieve this non-holomorphic modular symmetries come to rescue. Advantage of the current construction is the compactness of the model content and absence of the supersymmetric fields. Neutrino mass is generated through a canonical scotogenic mechanism. The allowed values of the VEV of the $\tau$ modulus are $\tau \simeq w$ and Im$[\tau ]\approx 2$. The non-holomorphic modular ${\mathcal{A}}_4$ symmetry leads to correlations among the neutrino observables.
