SIMULATION STUDIES ON CP AND CPT VIOLATION IN B(B)OVER-BAR MIXING - ART. NO. 036003

A simulation study is carried out for evaluating the experimental sens itivities of the BELLE detector at KEK's B factory on CP and CPT viola ting effects in B-0(B) over bar(0) mixing. CP violating effects are ex amined in terms of the charge asymmetries of same-sign dilepton events and single lepton events. The CPT violating effect is examined in ter ms of the time evolution of the opposite-sign dilepton events. As a by -product, it is shown that a precise extraction of the B-0(B) over bar (0) mixing parameter x(d) and the B lifetime tau(B) is possible from t he proper time distribution of the same-sign dilepton events.
