Quark masses and mixing from Modular $S_4^{\prime }$ with Canonical Kähler Effects

Ivo de Medeiros Varzielas, Manuel Paiva

We propose a quark flavor model based on modular $S_4^{\prime }$ with a general CP symmetry. CP violation in the quark sector is entirely realized by the modulus $⟨\tau ⟩$. We show…
