Abstract

In a two Higgs-doublet model with D4 flavor symmetry we establish a relation between tanβ and the Cabibbo angle. Due to a small number of parameters, the quark Yukawa sector of the model is very predictive. The flavor changing neutral currents are small enough to allow for relatively light nonstandard scalars to pass through the flavor constraints.
