# Inverse seesaw model with a modular S 4 symmetry: lepton flavor mixing and warm dark matter

@article{Zhang2021InverseSM, title={Inverse seesaw model with a modular S 4 symmetry: lepton flavor mixing and warm dark matter}, author={Xinyi Zhang and Shun Zhou}, journal={Journal of Cosmology and Astroparticle Physics}, year={2021}, volume={2021} }

In this paper, we present a systematic investigation on simple inverse seesaw models for neutrino masses and flavor mixing based on the modular S 4 symmetry. Two right-handed neutrinos and three extra fermion singlets are introduced to account for light neutrino masses through the inverse seesaw mechanism, and to provide a keV-mass sterile neutrino as the candidate for warm dark matter in our Universe. Considering all possible modular forms with weights no larger than four, we obtain twelve… Expand
