CP Violation in Decays
نویسنده
چکیده
The origin of CP violation remains a mystery in particle physics. So far, CP -odd signals have been observed only in the kaon systems. To determine the source and nature of CP violation, it is necessary to observe it in several di erent processes. For a number of years theoretical e orts have been made to study it in the weak decays of hyperons belonging to the baryon octet [1{3]. Here, we present the results of a recent study exploring CP violation in the nonleptonic decays of the hyperon [4]. The CP -violating observable that we are considering is the rate-asymmetry for ! decays. It is given by

The discovery of CP violation in B-meson decays
We present the KEK B-factory project, which discovered CP violation in B-meson decays and proved that the Kobayashi-Maskawa theory correctly explains CP violation in meson decays.

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...
متن کاملTheory of CP Violation
CP violation in K and B decays is reviewed in the Standard Model (SM) and beyond the SM. In K decays, one is seeking first evidence for CP violation in direct K -+ ~rTr decays. This would not give a precise quantitative test for the present explanation of CP violation in terms of a phase in the Cabibbo-Kobayashi-Maskawa (CKM) matrix. Such tests are provided by a variety of CP asymmetries in neu...
متن کاملCp Violation -a New Era
We give a pedagogical review of the theory of CP violation with emphasis on the implications of recent experimental results. The review includes: (i) A detailed description of how CP violation arises in the Standard Model and in its extension that allows for neutrino masses; (ii) The formalism of CP violation in meson decays and its application to various K decays (ε K , ε ′ /ε and K → πνν), D ...
متن کاملRare Decays, CP Violation and QCD
We discuss several aspects of rare decays and CP violation in the standard model including the impact of the recent top quark discovery. In particular we review the present status of next-to-leading QCD calculations in this field stressing their importance in the determination of the parameters in the Cabibbo-Kobayashi-Maskawa matrix. We emphasize that the definitive tests of the standard model...
متن کاملCp Violation in B Decays
The role of B decays in the study of CP violation is reviewed. We treat the interactions and spectroscopy of the b quark and then introduce CP violation in B meson decays, including time-dependences, decays to CP eigenstates and non-eigenstates, and flavor tagging. Additional topics include studies of strange B’s, decays to pairs of light pseudoscalar mesons, and the roles of gluonic and electr...
