Description

A $SU(3)_C\times SU(3)_L \times U(1)_X$ extension of the gauge symmetry of the Standard Model with $A_4$ modular symmetry and radiative linear seesaw is proposed. The gauge extension of the SM offer an opportunity to add new scalar fields to the model that can be used in Yukawa interactions to construct the neutrino mass matrix. In addition, $A_4$ modular symmetry is used as a flavour symmetry to forbid some entries in the neutrino mass matrix at tree level but permitted at one-loop. This model can successfully accommodate the observables of the neutrino sector.
