Transverse Muon Polarization in $K^{\pm }\to {\pi }^0{\mu }^{\pm }\nu$ Decay Induced by the Two-Photon Final-State Interaction

Abstract

We calculate the transverse muon polarization in the decay $K^{\pm }\to {\pi }^0{\mu }^{\pm }\nu$ induced by the electromagnetic two-photon final-state interaction. For the central part of the Dalitz plot the typical value of this polarization is about $4\times 10^{-6}$.
