Abstract

We construct a model where the smallness of the masses of first quark generations implies the near block diagonal nature of the Cabibbo-Kobayashi-Maskawa matrix and vice versa. For this setup, we rely on a two Higgs-doublet model structure with an S₃ symmetry. We show that an SM-like Higgs emerges naturally from such a construction. Moreover, the ratio of two VEVs, tan\ensuremathβ, can be precisely determined from the requirement of the near masslessness of the up- and down-quarks. The flavor changing neutral current structure that arises from our model is also very predictive.
