Little Randall-Sundrum models: εK strikes again

Description

A detailed phenomenological analysis of neutral kaon mixing in 'little Randall-Sundrum' models is presented. It is shown that the constraints arising from the CP-violating quantity εK can, depending on the value of the ultraviolet cutoff, be even stronger than in the original Randall-Sundrum scenario addressing the hierarchy problem up to the Planck scale. The origin of the enhancement is explained, and a bound ΛUV>several 103 TeV is derived, below which vast corrections to εK are generically unavoidable. Implications for nonstandard Z0→bb couplings are briefly discussed.
