A study of 13.3\ifmmode\times\else\texttimes\fi{}${10}^{6}$ stopped ${K}^{+}$ in a heavy-liquid bubble chamber yielded 269 ${K}_{e4}$ decays the type ${e}^{+}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}\ensuremath{\nu}$, total greater by factor 4 than number found previous experiment. No examples ${e}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{+}\overline{\ensuremath{\nu}}$ were found. With 95% confidence, upper limit for decay rate...
The muonic decay of charmed strange mesons has been observed directly, in the analysis a sample 144 decays charged particles into muon and no other particle. branching ratio is estimated to be BR(Ds± →µ±νµ) = (4.0+1.8+0.8-1.4-0.6 ±1.7) ×10-3, assuming r 0.27 between production cross sections Ds± neutral particles. constant fDs (232 ±45 ±20 ±48) MeV/c2 does not depend on theoretical assumptions.
