Higgs Physics at the Linear Collider

We review the theory of Higgs bosons, with emphasis on the Higgs scalars of the Standard Model and its non-supersymmetric and supersymmetric extensions. After surveying the expected knowledge of Higgs boson physics after the Tevatron and LHC experimental programs, we examine in detail expectations for precision Higgs measurements at a future e+e- linear collider (LC). A comprehensive phenomenological profile can be assembled from LC Higgs studies (both in e+e- and gamma-gamma collisions). The Giga-Z option can provide important constraints and consistency checks for the theory of electroweak symmetry breaking.

Bounding CPT Violation in the Neutral-B System

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.
