Weak Mixing, CP Violation and the Standard Model

  • Konrad Kleinknecht
Conference paper

Abstract

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. 1.

    Weak Mixing of Quarks

     
  2. 1.1

    Kobayashi-Maskawa-Matrix

     
  3. 1.2

    Experimental Constraints on the KM Matrix

     
  4. 1.3

    Allowed Ranges of Mixing Angles for 3 or 4 Generations

     
  5. 2.

    CP Violation

     
  6. 2.1

    Phenomenology and Models

     
  7. 2.2
    New Experiments on ε′ / ε
    • E731 at Fermilab

    • NA31 at CERN: First Evidence for Direct CP Violation

     
  8. 3.

    Implications of Experimental Results on the Standard Model Parameters

     
  9. 4.

    Beyond the Standard Model: Searches for Rare Kaon Decays
