About 50 years ago John St. Bell published his famous Bell theorem that initiated a new field in physics. This contribution discusses how discrete symmetries relate to the big open questions of quantum mechanics, in particular:
(i) how correlations stronger than those predicted by theories sharing randomness (Bell's theorem) relate to the violation of the CP symmetry and the P symmetry; and its relation to the security of quantum cryptography,
(ii) how the measurement problem ("why do we observe no tables in superposition?") can be polled in weakly decaying systems,
(iii) how strongly and weakly interacting quantum systems are affected by Newton's self-gravitation.
These presented preliminary results show that the meson-antimeson systems and the hyperon-antihyperon systems are a unique laboratory to tackle deep fundamental questions and to contribute to the understand what impact the violation of discrete symmetries has.- Organisation(en)
