Modular S 3 flavored Pati-Salam model with a two family seesaw mechanism
Year: 2025
Type: article
Abstract: We present a unified model of quarks and leptons with modular S 3 flavor symmetry, where the two lightest family masses are naturally suppressed via a Pati-Salam version of the type I seesaw mechanism, mediated through heavier vectorlike fermions. Majorana neutrino masses are further suppressed through a double seesaw mechanism. The viable parameter space has a preferred range of the modulus field with Im ( τ ) ∼ 2 , leading to successful fermion masses and mixing. The prediction for neutrinoless double beta decay is partly within the reach of the nEXO experiment. In particular, the Dirac C P violating neutrino oscillation phase is predicted to lie in the range δ C P ν ∼ 270 ° − 360 ° .
