19. Review on Bell-Steinberger relation

Dr Giancarlo D'Ambrosio (INFN, Naples)

CPT and QM tests

17. Review on CPT and decoherence measurements with Kaons

Dr Marianna Testa (Rome Univ., "La Sapienza")

5/23/07, 10:30 AM

CPT and QM tests

Neutral kaons provide one of the most sensitive systems to quantum mechanics and CPT violation. In the first part of the talk, I will review results on CPT violation searches in the kaon system from the CPLEAR, KLOE and KTeV experiments. In the second part I will present tests of quantum coherence related to CPT violation performed at CPLEAR and KLOE by studying the time...

59. Local Realism vs Quantum Mechanics with Entangled Neutral Kaons

Dr Gianni Garbarino (Universita di Torino)

5/23/07, 11:20 AM

CPT and QM tests

We review recent proposals of Bell's inequality tests with entangled pairs of neutral kaons from $phi$ resonance decays. The suggested experiments are discussed in the light of the essential requirements for a genuine discrimination between Local Hidden-Variable Theories (i.e., Local Realism) and Quantum Mechanics. After showing that the tests proposed up to now can hardly (or...

72. Erasing the Past and Impacting the Future with Kaons at a Phi-factory

Dr Beatrix Hiesmayr (Vienna University)

5/23/07, 11:40 AM

CPT and QM tests

Two hundred years ago Thomas Young taught us that photons interfere. Nowadays also experiments with very massive particles, like the fullerenes, have impressively demonstrated that fundamental feature of quantum mechanics. Later studies have shown that the knowledge on the path through the double slit is the reason why interference is lost. The gedanken experiment of Scully and...

83. EPR entanglement and decoherence in Upsilon(4S) decays to B0-B0bar

Dr Apollo Go (National Central University of Taiwan)

5/23/07, 12:00 PM

CPT and QM tests

The neutral B-meson pair produced at Upsilon(4S) exhibits a non-local EPR-type entanglement. At Belle experiment at KEK, we measure this entanglement using time-dependent flavour asymmetry of semileptonic B0 decays and compare with prediction of quantum mechanics and two realistic models. We also measure the decoherence of the neutral B-meson pair in B0-B0bar and BH-BL basis.

16. CPT and Decoherence in Quantum Gravity

Prof. Nikolaos Mavromatos (King's College, London)

5/24/07, 9:00 AM

CPT and QM tests

I will give an overview of theoretical reasons for expecting a possible violation of CPT symmetry in some models of Quantum Gravity and then I will proceed to discuss experimental signatures of such a violation. As CPT violation may be (but not necessarily) linked to Lorentz Invariance Violation (LIV), a seizable portion of the talk will be devoted to tests of Lorentz symmetry...
