CP Violation and Quantum Mechanics in the B System

Abstract

We discuss the testing of the Standard Model of CP violation, and the search for CP-violating effects from beyond the Standard Model, in $B$ decays. We then focus on the quantum mechanics of the experiments on CP violation to be performed at $B$ factories. These experiments will involve very pretty Einstein-Podolsky-Rosen correlations. We show that the physics of these experiments can be understood without invoking the ``collapse of the wave function," and without the mysteries that sometimes accompany discussions of EPR effects.
