| <hidden TTP97-15 Quark mixing, CP violation and rare decays after the top quark discovery > We review the highlights of quark mixing, particle-antiparticle mixing, CP |
| violation and rare K- and B-decays in the Standard Model. The top quark |
| discovery, the precise measurement of its mass, the improved knowledge of the |
| couplings $V_{cb}$ and $V_{ub}$, and the calculations of NLO short distance |
| QCD corrections improved considerably the predictions for various decay rates, |
| the determination of the couplings $V_{td}$ and $V_{ts}$ and of the complex |
| phase in the Cabibbo-Kobayashi-Maskawa matrix. After presenting the general |
| theoretical framework for weak decays, we discuss the following topics in |
| detail: i) the CKM matrix, its most convenient parametrizations and the |
| unitarity triangle, ii) the CP-violating parameter $\epsilon_K$ and |
| $B^0_{d,s}-\bar B^0_{d,s}$ mixings, iii) the ratio $\epsilon'/\epsilon$, |
| iv) the rare K-decays $K_L\to\pi^0e^+e^-$, $K^+\to\pi^+\nu\bar\nu$, |
| $K_L\to\pi^0\nu\bar\nu$ and $K_L\to\mu^+\mu^-$, v) the radiative decays |
| $B\to X_s\gamma$ and $B\to X_s l^+l^-$, vi) the rare B-decays $B\to |
| X_{s,d}\nu\bar\nu$ and $B_{d,s}\to l^+l^-$, vii) CP violation in neutral and |
| charged B-decays putting emphasis on clean determinations of the angles of the |
| unitarity triangle, and viii) the role of electroweak penguins in B-decays. We |
| present several future visions demonstrating very clearly the great potential |
| of CP asymmetries in B-decays and of clean K-decays such as $K^+\to\pi^+\nu |
| \bar\nu$ and $K_L\to\pi^0\nu\bar\nu$ in the determination of the CKM |
| parameters and in decisive testing of the Standard Model. An outlook for the |
| coming years ends our review. |
