where we use the rescaling y$_{5D}$ → $_{y$_{5D}$}$√$_{1 +}$ β , which produces the correct β → ∞ limit [81] and avoids subtleties in the β = 0 case. With anarchical 5D Yukawa matrices, an RS residual little CP problem remains [80]: Too large contributions to the neutron electric dipole moment (EDM) [69], and sizable chirally enhanced contributions to ϵ$_{K}$ [12, 78, 82–84] are predicted. The RS leading contribution to ϵ$_{K}$ is generated by a tree-level KK-gluon exchange which leads to an effective coupling for the chirality-flipping operator in (6.3) of the type [78, 82–84] The final expression is independent of the f$_{x}$ i , so the bound in Table I can be translated into constraints in the y$_{5D}$ − M$_{KK}$ plane. The analogous effects in the D and B systems yield numerically weaker bounds. Another class of contributions, which involves only left-handed quarks, is also important to constrain the f$_{Q}$ − M$_{KK}$ parameter space. TABLE VI: Values of the f$_{x}$ i parameters [Eq. (6.4)] which reproduce the observed quark masses and CKM mixing angles starting from anarchical 5D Yukawa couplings. We fix f$_{U}$ 3 = √$_{2 and}$ y$_{5D}$ = 2 (see text). TABLE VII: Most significant flavor constraints in the RS framework. The values of y min 5D and f max Q 3 correspond to M$_{KK}$ = 3 TeV. The bounds are obtained assuming maximal CPV phases and g$_{s}$$_{∗}$ = 3. Entries marked ‘above (6.7)’ imply that for M$_{KK}$ = 3 TeV, y$_{5D}$ is outside the perturbative range.
