Abstract
We discuss modifications to the concept of an “antiparticle,” induced by a breakdown of the symmetry at a fundamental level, realized within an extended class of quantum gravity models. The resulting loss of particle-antiparticle identity in the neutral-meson system induces a breaking of the Einstein-Podolsky-Rosen correlation imposed by Bose statistics. This is parametrized by a complex parameter associated with the contamination by the ”wrong symmetry” state. The physical consequences are studied, and novel observables of violation in factories are proposed.
