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 violation, rare $K\to\pi\nu\overline{\nu}$ decays and in + particular the $B$-meson system are much more promising in this respect. + After a brief look at the $K$ system, selected aspects of CP-violating + effects in $B$ decays are discussed. It is pointed out that combined + branching ratios for $B\to\pi K$ modes, which have been observed recently + by the CLEO collaboration, may allow to derive stringent constraints on the + CKM angle $\gamma$ that could open a window to new physics. + + + |**Robert Fleischer**  | + |**     Proceedings of the 5th International Conference on Physics Beyond the Standard Model, Balholm, Norway, 29 Apr - 4 May 1997.
