Abstract: | For the decay process K + → μ + νγ, the effect of muon transverse polarization caused by electromagnetic final-state interaction is analyzed. It is shown that, in the one-loop approximation, the muon transverse polarization varies from ?1.3×10?3 to zero in the region of the Dalitz plot. The mean value of the muon polarization, 〈P T〉, in the kinematical region E γ ≥20 MeV is ?5.44×10?4. |
