Muon transverse polarization in the $K_{l2\gamma }$ process within the SM and three Higgs doublets Weinberg model

V. V. Braguta, A. A. Likhoded, A. E. Chalov

We consider two possible sources of the $T$-violating muon transverse polarization in the process $K^{+}\to {\mu }^{+}\nu \gamma$: electromagnetic final state interaction in the SM and contributi…
