CP Violation and Rare Kaon Decays

We summarize both the study of CP violation with $K$ and $B$ mesons, as well as rare decays of kaons, emphasizing recent developments. The topics discussed include the unitarity triangle, ${ϵ}^{\mathrm{\prime }}\mathrm{/}ϵ$, $K\to \pi \nu \bar{\nu }$ and other rare $K$ decays, T-odd asymmetries in kaon physics, theoretical aspects of CP violation in B decays, $B\to J\mathrm{/}\mathrm{\Psi }{K}_S$, $B\to \pi \pi$, $B\to \pi K$ and inclusive CP asymmetries.
