Description

I will report on recent studies of the decays K^+->pi^+pi^0e^+e^- and K_S->pi^+pi^-e^+e^-, focusing on their role as chiral tests. I will discuss how a precise enough measurement of any of these decay modes at CERN would help to complete the experimental determination of the NLO chiral counterterms involved in radiative kaon decays. I will also comment on the existing theoretical estimates for these counterterms and to what extent they are compatible with the present experimental numbers.
