BoundingCPTviolation in the neutralBsystem

The feasibility of placing bounds on $\mathrm{CPT}$ violation from experiments with neutral $B$ mesons is examined. We consider situations with uncorrelated mesons and ones with either unboosted or boosted correlated mesons. Analytical expressions valid for small $T$- and $\mathrm{CPT}$-violating parameters are presented for time-dependent and time-integrated decay rates, and various relevant asymmetries are derived. We use Monte Carlo simulations to model experimental conditions for a plausible range of $\mathrm{CPT}$-violating parameters. The treatment uses realistic data incorporating background effects, resolutions, and acceptances for typical detectors at CERN LEP, CESR, and the future $B$ factories. Presently, there are no bounds on $\mathrm{CPT}$ violation in the $B$ system. We demonstrate that limits of order 10% on $\mathrm{CPT}$ violation can be obtained from data already extant, and we determine the $\mathrm{CPT}$ reach attainable within the next few years.
