New Physics and Future B Factories

Abstract

Further experimental and theoretical studies of the physics of flavor and CP violation are well motivated. Within the supersymmetric framework, higher precision measurements will allow to explore classes of models with stronger degree of universality: first, models with no universality, such as alignment or heavy first two squark generations; second, models with approximate universality, such as dilaton dominance or AMSB; and finally models of exact universality, such as GMSB. A broad program, including various rare processes or CP asymmetries in B, D and K decays, will provide detailed information about viable extensions of the Standard Model. Some highlights of future B-physics experiments (the present B-factories with integrated luminosity of 0.5 ab^{-1}, hadron machines, and future high-luminosity B-factories) are described.
