Recent developments in nonleptonic kaon decays    [PDF]

Oscar Cata
I review the current status of nonleptonic kaon decays, placing special emphasis on the recent theoretical progress. In particular, I concentrate on 3 points: (i) the improved determination of \epsilon_K, including both perturbative and nonperturbative contributions; (ii) the efforts to tame (K -> 2\pi) transitions in lattice QCD; and (iii) the use of holographic methods to solve the vector meson dominance puzzle in (K -> 3\pi).
