A more novel approach of radiative linear seesaw in a modular $A_4$ symmetry

Abstract

We propose a radiatively induced linear seesaw model that is perfectly realized at leading order by a modular $A_4$ symmetry. Because this group also has a flavor symmetry, we obtain some predictions concentrating on two specific regions at nearby fixed points $\tau =\omega$ and $i$. Through our numerical chi square analysis, we show predictions for each the case depending on the neutrino mass ordering; normal and inverted one.
