Teil 6A: Nikolaos Mavromatos: Quantum Gravity and Entangled Particle States (erster Teil)

Moderation: Beatrix Hiesmayr

Some Quantum Gravity models entail a foamy structure for space time at microscopic (Planck-)scales. Matter in such backgrounds may experience quantum decoherence, as a result of information being carried out by gravitational degrees of freedom, not accessible by local scattering experiments. Concrete examples of such models may be provided by string theory with space-time membrane defects. In all such models, the quantum CPT operator of the effective field theory of the low-energy degrees of freedom may be "pertubatively ill-defined" leading to modifications in the Einstein-Podolsky-Rosen (EPR) correlators in entangled particle states. These may be falsifiable in future upgraded facilities of neutral mesons, for instance a possible upgrade of DaFNE detector or B-mesons. Complementary tests / bounds of such a decoherence may also be provided by cosmic neutrino and high-energy photon astronomies.
