 +   <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.
