On a possible EPR experiment with $B^{0}_{d}\bar{B^{0}_{d}}$ pairs

Abstract

A very general local realistic theory of single $B^{0}_{d}$ mesons and of correlated $B^{0}_{d}\bar{B^{0}_{d}}$ pairs is formulated. If these pairs are produced in the $Υ(4S)$ decay, the local realistic asymmetry for observing pairs with like and unlike flavour at different proper times remarkably differs from the quantum mechanical prediction. Asymmetric B-factories provide a powerful tool for the study of the EPR problem since the relative detection experiments are shown to be capable of a time-dependent measurement precise enough to discriminate between local realism and quantum theory.
