Quantum [Un]Speakables II: 50 Years of Bell's Theorem Mitschnitt einer Veranstaltung am Donnerstag, dem 19. Juni 2014 im Lise Meitner-Hörsaal der Fakultät für Physik der Universität Wien Teil 11: Vortrag von Beatrix Hiesmayr: "Testing Bell's Theorem in High Energy Physics" Beatrix Hiesmayr arbeitet an der Fakultät für Physik der Universität Wien. Abstract: The aim of this talk is to discuss whether Bell's theorem can be brought back to those systems that do not build up ordinary matter and light. Indeed, entanglement can be witnessed, e.g., in flavour oscillating systems, in particular in the neutral kaon-antikaon system, But: Can an experimentally conclusive test be found proving the existence of correlations that are stronger than those allowed by classical physics? The first thing to note is that it is not straightforward to apply his theorem to decaying two-state systems. From the theoretical point of view the findings turned out to be surprising since a connection between the violation of Bell's theorem and the tiny violation of the CP symmetry has been found. The broken CP symmetry, verified in various accelerator facility experiments, reveals a small difference of a world of matter and a world of antimatter. Moreover, this discovery of CP violation can be attributed to the unsolved problem why we live in a universe dominated by matter, a huge open problem in particle physics.
