A More Novel Approach of Radiative Linear Seesaw in a Modular <i>A</i>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 case of normal or inverted neutrino mass ordering.
