We discuss the testing of the Standard Model of CP violation, and the search for CP-violating effects from beyond the Standard Model, in $B$ decays. We then focus on the quantum mechanics of the experiments on CP violation to be performed…
We consider the possibilities of testing CP conservation in the process $e^+e^- \rightarrow ZH$. The easiest is to measure the forward-backward asymmetry of the $Z$ boson, a nonzero value of which signals CP violation. The effects of CP…
Measurements of CP--violating observables in neutrino oscillation experiments have been studied in the literature as a way to determine the CP--violating phase in the mixing matrix for leptons. Here we show that such observables also probe…
Experimental prospects for observing CP violation in B-meson decays are reviewed. Comparisons are made for various options: experiments at $e^+ e^-$ B-Meson Factories, HERA and the TEVATRON will produce results in near future. They will…
We describe some of the extensions of the SM, including models with spontaneous CP violation, where New Physics relevant for CP violation may arise. It is emphasized that the SM predicts a series of exact relations among various measurable…
CP violation in hadronic B-decays is studied in a definite and well motivated framework of flavour physics and supersymmetry. Possible deviations from the standard model both in mixing and in decay amplitudes are discussed. An attempt is…
Several pieces of direct and indirect evidence now suggest that the Kobayashi-Maskawa mechanism plays a distinguished role for CP violation at the electroweak scale. This talk provides a general overview of CP violation in its various…
We discuss the history of CP violation and its manifestations in kaon physics, its explanation in terms of phases of the Cabibbo-Kobayashi-Maskawa matrix describing charge-changing weak quark transitions, predictions for experiments…
Several recent results from the NA48 experiment are presented: a measurement $|\eta_{+-}|$, search for CP violating phenomena in $K^\pm\to3\pi$ decays, and a measurement of $|V_{us}|$.
Recent results on searches for CP and CPT violation in the charm sector are presented. These results include limits on direct CP violation in several channels from the FOCUS and CLEO experiments. The first reported search for CPT violation…
After summarizing the status concerning CP violation in 1998 I describe the exciting developments of the last two years and extrapolate to the future. I comment on recent lessons about T and CPT invariance maninly from CPLEAR and emphasize…
We estimate CP violation for several experimental facilities studying neutrino oscillations. We also estimate the probability of $\nu_{\mu}$ to $\nu_{e}$ conversion, using values of the parameter $\theta_{13}$ within the known limits, 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…
Although CP violation is predicted to be small in the Standard Model, there exists a continuing theoretical interest within the charm sector due to enhancements of CPV through new physics processes. We present an overview of the…
This lecture provides a general overview of CP violation, emphasizing CP violation in flavour-violating interactions, such as due to the Kobayashi-Maskawa mechanism.
Loop corrections for physics beyond the Standard Model are computed. DWe discuss the influence of new physics on CP-violating observables. Assuming the standard model gives a correct description of tree level processes, we show how a…
At present, there are discrepancies with the predictions of the standard model in ${\bar B}^0 \to D^{*+} \ell^- {\bar\nu}_\ell$ decays, hinting at the presence of new physics (NP) in $b \to c \tau^- {\bar\nu}$. Various NP models have been…
CP violation in top physics is reviewed. The Standard Model has negligible effects, consequently CP violation searches involving the top quark may constitute the best way to look for physics beyond the Standard Model. Non-standard sources…
We present results on CP violation from approximately 2.8 fb^{-1} of data collected by the D0 Experiment at the Fermilab Tevatron. The results presented are: (i) an improved measurement of the B_s^0 CP-violating phase from a flavor-tagged…
The CP properties in hyperon decays are briefly reviewed. We discuss the general phenomenology and define CP odd observables in hyperon decays. With these observables, we discuss the predictions of some models and their observational…
