| Popis: | The CPLEAR experiment measured time-dependent decay-rate asymmetries of K-0 and (K) over bar(0) decaying to pi(+)pi(-)pi(0) in order to study the interference between the decay amplitudes of K-S(0) - either CP-violating or CP-conserving - and the CP-conserving K-L(0) decay amplitude. From the analysis of the complete data set we find for the CP-violating parameter eta(+-0), Re((+-0)) = (-2 +/- 7 stat. (+4)(-1) syst.) x 10(-3), Im(eta(+-0)) = (-2 +/- 9 stat. (+2)(-1) syst.) x 10(-3) and for the CP-conserving parameter lambda, Re(lambda) = (+28 +/- 7 stat. +/-3 syst.) x 10(-3), Im(lambda) = (-10 +/- 8 stat. +/- 2 syst.) x 10(-3). From the latter, the branching ratio of the CP-conserving (KS)-S-0 --> pi(+)pi(-)pi(0) decay is deduced to be B = (2.5(-1.0)(+1.3) stat. (+0.5)(-0.6) systs.) x 10(-7). (C) 1997 Elsevier Science B.V.
