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.

Violation of CPT and quantum mechanics in the − system

Patrick Huet, Michael E. Peskin

We reconsider the model of quantum mechanics violation in the K0−K0 system, due to Ellis, Hagelin, Nanopoulos, and Srednicki, in which CP- and CPT-violating signatures arise from the evolution of pure states into mixed states. We present a formalism for computing time-dependent asymmetries in this model and show that present data constrains its parameters significantly. In the future, this model will be put to very stringent tests at a ø-factory. We present the theory of these tests and show the relation between particular ø-decay correlations and the parameters of quantum mechanics violation.We reconsider the model of quantum mechanics violation in the K0−K0 system, due to Ellis, Hagelin, Nanopoulos, and Srednicki, in which CP- and CPT-violating signatures arise from the evolution of pure states into mixed states.
