We consider the \(A_4\) realization of linear seesaw by extending the standard model (SM) particle content with two types of right-handed neutrinos along with the flavon fields, and the SM symmetry with \(A_4\times Z_4\times Z_3\) and a global symmetry \(U(1)_X\). We also discuss the scope of this model to explain the baryon asymmetry of the Universe through leptogenesis.
