Cheung, Clifford, Andrew Liam Fitzpatrick, and Lisa Randall. 2008. Sequestering CP violation and GIM-violation with warped extra dimensions. Journal of High Energy Physics 2008(1): 69.Abstract
We propose a model of spontaneous CP violation to address the strong CP problem in warped extra dimensions that relies on sequestering flavor and CP violation. 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 \(10^{−12}\).Other Sources
