【 摘 要 】

We discuss theoretical issues in radiative rare kaon decays. The interest is twofold: to extract useful short-distance information and understand the underlying dynamics. We emphasize channels where either we can understand non-perturbative aspects of QCD or there is a chance to test the Standard Model. An interesting channel, K+→ π+π0e+e-, is studied also in connection with the recent experimental NA48 results. Motivated by LHCB results on KS→ μ+μ-we discuss other channels like KS,L→ l+l-l+l-. Motivated by recent theoretical work by Buras and collaborators we study also the K±→ π±l+l-form factor.
