Abstract

We review and update the effects of physics beyond the standard model on CP asymmetries in B decays. These asymmetries can be significantly altered if there are important new-physics contributions to

B_{q}^{0} - \bar{B_{q}^{0}}

mixing. This same new physics will, therefore, also contribute to rare, flavor-changing B decays. Through a study of such decays, we show that it is possible to partially distinguish the different models of new physics.
