High Energy Physics:

A study of quantum correlations in neutral mesons reveals features not seen in stable quantum systems and on the other hand, the use of open system ideas on these systems leads to predictions that suggest a rethinking of the interpretation of important observables in particle physics and also suggests background effects which could be possible signatures of quantum gravity. Quantum Correlations imply neutrino oscillations and vice versa.
