Study of Λ+ c Semileptonic Decays. Search for Time-Reversal Violation
Résumé
Until 1964, Time-Reversal symmetry was naively assumed to be conserved in weak interactions as well as in electromagnetic and strong interactions. Therefore the discovery of CP violation was completely unexpected when, in 1964, Val Fitch, Jim Cronin and other collaborators observed this phenomenon for the first time in the weak decays of neutral kaons. This discovery came out with a remarkable thing that has to do with Time-Reversal symmetry. According to the logic of CPT Theorem, one of the most basic concepts of particle physics, the violation of CP leads us to admit the violation of Time-Reversal symmetry in an indirect way.
