We assume that brane-localized Higgs Yukawa interactions respect a $$U(3)$$ flavor symmetry that is broken only by bulk fermion mass and Yukawa terms. All CP violation arises from the vev of a CP-odd scalar field localized in the bulk. To suppress radiative corrections to $$\bar{\theta}$$, the doublet quarks in this model are localized on the IR brane. We calculate constraints from flavor-changing neutral currents (FCNCs), precision electroweak measurements, CKM unitarity, and the electric dipole moments in this model and predict $$\bar{\theta}$$ to be at least about $$10^{−12}$$.
