Abstract

The Z₂ gauging of Z_N symmetry can enforce certain elements of the fermion Yukawa couplings to vanish. We have performed a systematical study of texture zero patterns of lepton mass matrices in the minimal seesaw model, and we present all the possible patterns of the charged lepton Yukawa coupling Y_E, neutrino Yukawa coupling Y_ν, right-handed neutrino mass matrix M_R and the light neutrino mass matrix M_ν which can be derived from the Z₂ gauging of Z_N symmetry. The realization of the textures with the maximum number of zeros and the second maximum number of zeros from non-invertible symmetry is studied, and the phenomenological implications in neutrino oscillation are discussed.
