摘要：

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 epsilon(K) 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 Lambda(UV)> several 10(3) TeV is derived, below which vast corrections to epsilon(K) are generically unavoidable. Implications for nonstandard Z(0)-> b(b)over bar couplings are briefly discussed.
