Although CP violation in the B meson system has been well established by the B factories, there has been no direct observation of time reversal violation. The decays of entangled neutral B mesons into definite flavor states ($B^0$ or…

We present the general form of the decay width angular distributions with T-odd terms in $B\to K \phi \phi$ decays. We concentrate on the T violating effects by considering various possible T-odd momentum correlations. In a generic class of…
If new CP violating physics contributes to neutral meson mixing, but its contribution to CP violation in decay amplitudes is negligible, then there is a model independent relation between four (generally independent) observables related to…
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 $K\to \pi\pi$ decays. This would not give a precise quantitative test for the…
A review of CP violation in the $B$ system and strategies to determine the unitarity triangle of the CKM matrix is given. We begin with an introduction to the description of CP violation in the Standard Model of electroweak interactions,…
The BABAR and Belle experiments have made detailed studies of time-dependent CP violation in the B meson sector. If CPT is conserved, CP violation should imply the presence of time-reversal violation. Production of entangled neutral B…
The present status of CP violation in decays of neutral kaons is reviewed. In addition selected rare decays of both K and B mesons are discussed. The emphasis is in particular on observables that can be reliably calculated and thus offer…
We propose to use T-odd momentum correlations as physical observables to study T violation in $B\to K^{*}l^{+}l^{-} (l=e,\mu)$ decays. We show that these observables are zero in the standard model but sizable at the level of 10% in the…
A brief review of CP violation in $K$ and $B$ decays is given. While the observables $\varepsilon$ and Re$(\varepsilon'/\varepsilon)$ describing CP violation in neutral $K$ decays do not allow a powerful test of the CKM mechanism of CP…
After an introduction to the Standard-Model description of CP violation, we turn to the main focus of these lectures, the B-meson system. Since non-leptonic B decays play the key role for the exploration of CP violation, we have to discuss…
This review of CP violation focuses on the status of the subject and its likely future development through experiments in the Kaon system and with B-decays. Although present observations of CP violation are perfectly consistent with the CKM…
We present an analysis of CPT violation in $B\to J/\psi K$ decays. A method of kaon regeneration is proposed to increase the $K_{S(L)}$ interference effects. With the time evolution of both neutral B and K mesons, we show that it is…
CP violations in B meson decays at hadron colliders are reviewed. In particular I examine: $B^0-\bar{B^0}$ mixing and oscillations within Standard Model and the Cabibbo-Kobayashi-Maskawa picture for CP violations; $B^0$ decays into CP…
CP violation in the K system is pedagogically reviewed. We discuss its manifestations in the neutral K meson systems, in rare K meson decays and in decays of charged K mesons. Results from classical experiments, and perspectives for…
CP violation in $B\to J/\psi K^*$ decays is studied using an angular analysis in a data sample of 253 fb$^{-1}$ recorded with the Belle detector at the KEKB $e^+e^-$ collider. The flavor separated measurements of the decay amplitudes…
We discuss the concepts and methodology to implement an experiment probing directly Time Reversal (T) non-invariance, without any experimental connection to CP violation, by the exchange of "in" and "out" states. The idea relies on the…
We review the subject of CP violation in the $B$ meson system within the Standard Model of CP violation, which is based on a complex phase in the Cabibbo-Kobayashi-Maskawa (CKM) matrix. Three kinds of CP nonconservation are studied: In…
We study $T$ violation in the three-body charmless baryonic decay of $\bar B^0 \ra \Lambda \bar p \pi^+$ through the $T$-odd triple product correlation in the standard model. We find that the $T$ violating asymmetry is 10%, which is…
CP violation in $B$ decays is reviewed in the Standard Model (SM) and beyond the SM. The present explanation of CP violation in terms of a phase in the Cabibbo-Kobayashi-Maskawa (CKM) matrix can be tested through a variety of CP asymmetries…
