Abstract

We present a concise review of the recent theoretical progress concerning the standard model calculations of the rare K_L -> pi^0 nu anti-nu, K^+ -> pi^+ nu anti-nu (gamma), anti-B -> X_s gamma, and anti-B -> X_s l^+ l^- decays. The current status and future of the model-independent analysis of rare K- and B-meson decays within constrained minimal-flavor-violation is also briefly discussed.
