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 consider
multimoduli scenario, in which charged leptons and neutrinos are assigned to different moduli. Various
models are considered depending on different assignments of modular weights and the mechanism
for producing the light neutrino masses.
