    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...

    The NA48/2 experiment at CERN reports the first observation of the K± → π±π0e e− decay from an exposure of 1.7×1011 charged kaon decays recorded in 2003−2004. A sample of 4919 candidates with 4.9% background contamination allows the determination of the branching ratio in the full kinematic region. The study of the kinematic space shows evidence for a structure dependent contribution in...
