Measurements of the CKM parameter $\sin(2 \beta)$ have established $CP$ violation in the $B^0$ meson system arising from the interference between mixing and decay. However, direct CP violation, arising from the interference among different…
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 $K^0-\Kbar$ mixing, consistent with a…
Results by the BaBar and Belle experiments of the measurements $\sin 2\alpha$, $\sin 2\beta$ and $\sin (2\beta + \gamma)$ along with the CKM matrix elements $V_{cb}$ and $V_{ub}$ are presented. The BaBar and Belle experiments $b \to…

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…
We present preliminary measurements of CP-violating asymmetries in B decays. These include new results on the CKM angle alpha based on studies of the decay B -> rho+ rho- and several charmonium and hadronic penguin modes, sensitive to 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…
In the standard model, direct CP-violating asymmetries for $B^\pm \to \pi^\pm K$ are roughly 2% based on perturbative calculation. Rescattering effects might enhance it to at most (20-25)%. We show that lepton-number-violating couplings in…
We investigate the future determination of the CKM matrix using theoretically clean quantities, like $B(K^+\to\pi^+\nu\bar\nu)$, $B(K_L\to\pi^0\nu\bar\nu)$ or $\sin 2\beta$, $\sin 2\alpha$ as extracted from CP violation studies in $B$…
Measurements of CP asymmetries in B decays will soon be made at $B$ factories and hadron machines. In light of this, we review and update the profile of the CKM unitarity triangle and the resulting CP asymmetries in B decays. This is done…
The measurement of CP asymmetries in charged B meson decays might provide the first demonstration of CP violation outside the K system. Among the usual three CP-odd phases $\alpha$, $\beta$ and $\gamma$, the phase $\gamma$ seems to be the…
