A radiative seesaw model with three Higgs doublets in modular A4 symmetry

We propose a radiative seesaw model based on a modular A4 symmetry, which has good predictability in the lepton sector. We execute a numerical analysis to search for parameters that satisfy the experimental constraints such as those from neutrino oscillation data and lepton flavor violations. Then,...

Description
Summary:We propose a radiative seesaw model based on a modular A4 symmetry, which has good predictability in the lepton sector. We execute a numerical analysis to search for parameters that satisfy the experimental constraints such as those from neutrino oscillation data and lepton flavor violations. Then, we present several predictions in our model that originate from the modular symmetry at a fixed point as well as fundamental region of τ.
