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.
