A Possibility to Measure CP-Violating Effects in the Decay K --> mu nu gamma

Abstract

It is argued that a precise measurement of the transverse component of the muon spin in the decay K --> mu nu gamma makes it possible to obtain more stringent limits on CP-violating parameters of the leptoquark, SUSY and left-right symmetric models. The results of the calculations of the CP-even transverse component of the muon spin in the decay K --> mu nu gamma due to the final-state electromagnetic interactions are presented. The weighted average of the transverse component of the muon spin comprises 2.3 times 10^{-4}.
