Bounding CPT Violation in the Neutral-B System
Abstract
The feasibility of placing bounds on CPT violation from experiments with neutral- 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 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 CPT-violating parameters. The treatment uses realistic data incorporating background effects, resolutions, and acceptances for typical detectors at LEP, CESR, and the future factories. Presently, there are no bounds on CPT violation in the system. We demonstrate that limits of order 10\% on CPT violation can be obtained from data already extant, and we determine the CPT reach attainable within the next few years.
