CP Violation : Present and Future ∗

چکیده

We review the present status of CP violation in the standard model. Subsequently we make an excursion in the future in order to see what we could expect in this field in this and the next decade. We present various strategies for the determination of the CKM parameters and divide the decays into four classes with respect to theoretical uncertainties. We emphasize that the definitive tests of the Kobayashi-Maskawa picture of CP violation will come through a simultaneous study of CP asymmetries in B d,s decays, the rare decays K → πνν̄ and KL → πνν̄, and xd/xs. We illustrate how the measurements of the CP asymmetries in B d,s-decays together with a measurement of Br(KL → πνν̄) or Br(K → πνν̄) and the known value of | Vus | can determine all elements of the Cabibbo-Kobayashi-Maskawa matrix essentially without any hadronic uncertainties. ∗Invited talk given at the First International Conference on Phenomenology of Unification from Present to Future, Rome March 23-26, 1994, to appear in the proceedings. Supported by the German Bundesministerium für Forschung und Technologie under contract 06 TM 732 and by the CEC science project SC1–CT91–0729. CP Violation: Present and Future ∗

CP Violation – A Brief Review 1

Some past, present, and future aspects of CP violation are reviewed. The discrete symmetries C, P, and T are introduced with an example drawn from Maxwell’s Equations. The history of the discovery of CP violation in the kaon system is described briefly, and brought up-to-date with a review of recent results on kaon decays. The candidate theory of CP violation, based on phases in the Cabibbo-Kob...

We review the present status of the Standard Model of CP violation, which is based on a complex phase in the Cabibbo-Kobayashi-Maskawa (CKM) matrix. So far CP violation has been observed only in K −K mixing, consistent with a sizable phase. The implications of future CP nonconserving measurements in K and B decays are discussed within the model. Direct CP violation in K → 2π may be observed in ...

We consider the possibility of observing CP violation in quasi-inclusive decays of the type B does not contain strange quarks. We present estimates of rates and asymmetries for these decays in the Standard Model and comment on the experimental feasibility of observing CP violation in these decays at future B factories. We find the rate asymmetries can be quite sizeable. Observation of such asym...
