Abstract

We discuss radiative transitions of a charged kaon to a pion and two photons. In particular, we have a closer look at radiative corrections for the K+π++K^+\to\pi^+\ell^+\ell^- decays and present the branching ratio of the K+π+e+ee+eK^+\to\pi^+e^+e^-e^+e^- process calculated for the first time at leading order in the Standard Model.
