Violation of CPT and Quantum Mechanics in the K0--K0bar System
Abstract
We reconsider the model of quantum mechanics violation in the -- 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 factory. We present the theory of these tests and show the relation between particular decay correlations and the parameters of quantum mechanics violation.
