Abstract

We review some recent theoretical results on radiative rare kaon decays. Particular attention is devoted to the channels K πl% l and K ππγ, where we are (or might be) able to extract the short distance contributions. This is achieved by a careful study of the long distance part. We study also CP violating observables, which are sensitive also to extensions of the SM. As byproduct, we discuss interesting chiral tests.
