| Transverse Vuon Polarization in the $K_{l2\gamma}$ Decay Due to the Electromagnetic Final State Interaction | ||
| Protvino, 2000.-p.11, figs.4, refs.:9. | ||
The effect of the transverse muon polarization in the $K^+ \to \mu^+ \nu \gamma$ process, caused by the electromagnetic final state interaction, is analyzed. It is shown that for the one-loop calculations the value of the muon transverse polarization varies within $(0.0 \div 1.5\cdot 10^{-2})$ in the Dalitz plot region. Averaged value of the muon transverse polarization, $\langle P_T \rangle$, in the kinematic region of $E_\gamma \geq 20$~MeV is equal to $1.1\cdot 10^{-3}$.
