The main results on the CP violation measurements with neutral and charged kaons from the NA48 experiment at the CERN SPS are reviewed in this paper. The direct CP violating parameter Re(ε′/ε) has been measured by NA48 from the decay rates of neutral kaons into pion pairs. The final result, based on the data collected in 1997, 1998, 1999 and 2001, clearly established the existence of direct CP ...

The distributions of the single decay b-quarks and leptons from e+e− → tt̄ assuming CP violation are reviewed. Different asymmetries , sensitive independently to CP violation in the production and in the decay, and sensitive to the real and imaginary parts of d and d are defined. The analytic expressions are general and independent on the model of CP violation. In most of them all phase space in...

The phenomenon of CP violation is crucial to understand the asymmetry between matter and antimatter that exists in the Universe. Dramatic experimental progress has been made, in particular in measurements of the behaviour of particles containing the b quark, where CP violation effects are predicted by the Kobayashi-Maskawa mechanism that is embedded in the standard model. The status of these me...

This is a written version of a series of three lectures aimed at graduate students in the field of experimental high energy physics. The emphasis is on physics that is relevant to B-factories. The main topics covered are: (i) The flavor sector of the Standard Model; (ii) Determination of the mixing parameters; (iii) CP violation in meson decays (a model independent description); (iv) CP violati...

CP violation in the B-meson system has generated considerable experimental and theoretical interest, as potentially large e ects are expected. Searches for CP(T) violation using the small sample of Z ! b b decays at the LEP collider at CERN provide \proofs of principle" for analysis techniques which will be employed by future B-Factory experiments. Indirect CP violation is possible in the B sys...

■ Abstract Until recently, CP violation had been observed only in kaon decays. In order to conclusively interpret CP violation and test whether it can be explained in the framework of the Cabibbo-Kobayashi-Maskawa matrix, two asymmetric B factories, KEK-B and PEP-II, were constructed in the past decade. Recent measurements with the two detectors at these B factories clearly established large CP...

We have performed the first search for CP violation in tau lepton decay. CP violation in lepton decay does not occur in the minimal standard model but can occur in extensions such as the multi-Higgs doublet model. It appears as a characteristic difference between the τ and τ decay angular distributions for the semi-leptonic decay modes such as τ → Kπν. We define an observable asymmetry to explo...

We describe the role of CP violation in the generation of the baryon asymmetry of the Universe, in the framework of baryogenesis through leptogenesis, with emphasis on the possible relationship between CP violation at low energies and that required by leptogen-esis. It is emphasized that a direct link between these two manifestations of CP violation only exists in the framework of specific flav...

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...
