Abstract
Using events in which one of two neutral B mesons from the decay of an Y(4S) meson is fully reconstructed, we determine parameters governing decay (DeltaGamma(d)/Gamma(d)), CP, and T violation (\q/p\), and CP and CPT violation (Re z, Im z). The results, obtained from an analysis of 88x10(6) Y(4S) decays recorded by BABAR, are sgn(Re lambda(CP))DeltaGamma(d)/Gamma(d)=-0.008+/-0.037(stat)+/-0.018(syst)[-0.084,0.068], \q/p\=1.029+/-0.013(stat)+/-0.011(syst)[1.001,1.057],(Re lambda(CP)/'lambda(CP)') Re z=0.014+/-0.035(stat)+/-0.034(syst)[-0.072,0.101],Im z>=0.038+/-0.029(stat)+/-0.025(syst)[-0.028,0.104]. The values inside the square brackets indicate the 90% confidence-level intervals. These results are consistent with standard model expectations.
