Experimental study of the time-dependent rate of $K^{0} \rightarrow \pi^{+} \pi^{-} \pi^{0}$
The time-dependence of the decay rate of initially pure K/sup 0/ into the final state ( pi /sup +/ pi /sup -/ pi /sup 0/) has been studied in search for the decay K/sup 0//sub S/ to pi /sup +/ pi /sup -/ pi /sup 0/. No evidence is found in a sample of 384 observed events. The ratio of the CP-violati...

| description | The time-dependence of the decay rate of initially pure K/sup 0/ into the final state ( pi /sup +/ pi /sup -/ pi /sup 0/) has been studied in search for the decay K/sup 0//sub S/ to pi /sup +/ pi /sup -/ pi /sup 0/. No evidence is found in a sample of 384 observed events. The ratio of the CP-violating K/sup 0//sub S/ amplitude and the K/sup 0 //sub L/ amplitude is eta /sub +-0/=(0.13(+0.17-0.20))+i(0.17 (+0.27-0.26)); the ratio of the CP-conserving K/sup 0//sub S/ amplitude and K/sup 0//sub L/ amplitude is mod rho mod <0.4. The energy dependence of the K/sup 0/ to pi /sup +/ pi /sup -/ pi /sup 0/ matrix element is found to be a/sub +-0/=-0.31+or-0.03. (12 refs). |
