Weak Mixing, CP Violation and the Standard Model

1990

These lectures summarize experimental information on weak couplings of quark flavours from weak decays and weak production of heavy flavours and the relation of the observed direct CP violation to a non-trivial phase in the quark mixing matrix. The interest in this field is twofold: on the one side, we can measure precisely the parameters of the standard model in its own framework; on the other side, any inconsistency amongst these measurements or evidence for any process forbidden in the standard model will lead beyond that model. The outline of these lectures is the following: 1. Weak Mixing of Quarks 1.1 Kobayashi-Maskawa-Matrix 1.2 Experimental Constraints on the KM Matrix 1.3 Allowed R…

Models of CP Violation

2003

After the discovery of CP violation in K decay, a host of theoretical models was proposed to allocate this phenomenon to known interactions. Assuming CPT invariance of all interactions, the observed CP-violating effects in K decay imply also T violation. In general, with CPT invariance, there are four combinations of violations possible to be treated in this chapter
