Quantum Gravity, CPT symmetry and entangled states



There may be unique (“smoking-gun”) signatures of the breakdown of CPT symmetry, induced in some models of Quantum Gravity entailing decoherence for quantum matter. Such effects can be observed in entangled states of neutral mesons via modifications of the respective Einstein-Podolsky-Rosen (EPR) correlators (“ω-effect”). In the talk I discuss experimental signatures and bounds of the ω-effect in Φ- and B-factories, and argue that the effect might be falsifiable at the next generation facilities.

The experiment can independently measure all three decoherence parameters α,β, γ of Ellis et al. and hence test the assumption of complete positivity, which notably may not be a property of quantum gravity.)Google Scholar
