Bounding CPT Violation in the Neutral-B System
Alan Kostelecky, Rick Van Kooten
Abstract
The feasibility of placing bounds on 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 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 B factories. Presently, there are no bounds on CPT violation in the B 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.
