Violation of CPT and Quantum Mechanics in the K0--K0bar System

High Energy Physics - Phenomenology 2010-11-01 v2

Abstract

We reconsider the model of quantum mechanics violation in the \ko\ko--\kob\kob 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 ϕ\phi factory. We present the theory of these tests and show the relation between particular ϕ\phi decay correlations and the parameters of quantum mechanics violation.
