Fermion mass and mixing in a low-scale seesaw model based on the S₄ flavor symmetry

We construct a low-scale seesaw model to generate the masses of active neutrinos based on S₄ flavor symmetry supplemented by the Z₂ × Z₃ × Z₄ × Z₁₄ × U(1)ₗ group, capable of reproducing the low-energy Standard Model (SM) fermion flavor data. The masses of the SM fermions and the fermionic mixing parameters are generated from a Froggatt–Nielsen mechanism after spontaneous breaking of the S₄ × Z₂ × Z₃ × Z₄ × Z₁₄ × U(1)ₗ group. The obtained values for the physical observables of the quark and lepton sectors are in good agreement with the most recent experimental data. The leptonic Dirac CP-violating phase δ_CP is predicted to be 259.579° and the predictions for the absolute neutrino masses in the model can also saturate the recent constraints.
