Probing violation of quantum mechanics in the K0-(bar K)0 system

Patrick Huet

Michael E. Peskin

We reconsider the model of quantum mechanics violation in the K 0 -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 φ factory.We present the theory of these tests and show the relation between particular φ decay correlations and the parameters of quantum mechanics violation.

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.

A new approach to the dynamics of the K/sup 0/, K-bar/sup 0/ (S, S-bar) system is presented using discrete-time quantum mechanics and explicit T violations.
