Lepton Masses and Mixing in Modular A5 Symmetry

Abstract

A model based on the modular group A5 is considered to account for lepton masses and mixing. We con- sider multimoduli scenario, in which charged leptons and neutrinos are assigned to different moduli. Var- ious models are considered depending on different assignments of modular weights and the mechanis for producing the light neutrino masses.
