 ====== TTP9715 Quark mixing, CP violation and rare decays after the top quark discovery ====== 
 
 
 <hidden TTP9715 Quark mixing, CP violation and rare decays after the top quark discovery > We review the highlights of quark mixing, particleantiparticle mixing, CP 
 violation and rare K and Bdecays 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 CabibboKobayashiMaskawa 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 CPviolating parameter $\epsilon_K$ and 
 $B^0_{d,s}\bar B^0_{d,s}$ mixings, iii) the ratio $\epsilon'/\epsilon$, 
 iv) the rare Kdecays $K_L\to\pi^0e^+e^$, $K^+\to\pi^+\nu\bar\nu$, 
 $K_L\to\pi^0\nu\bar\nu$ 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 Bdecays $B\to 
 X_{s,d}\nu\bar\nu$ and $B_{d,s}\to l^+l^$, vii) CP violation in neutral and 
 charged Bdecays putting emphasis on clean determinations of the angles of the 
 unitarity triangle, and viii) the role of electroweak penguins in Bdecays. We 
 present several future visions demonstrating very clearly the great potential 
 of CP asymmetries in Bdecays and of clean Kdecays 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.
