Abstract
We study the decays KâÏÏ in one-loop two-flavour Chiral Perturbation Theory. We provide arguments why the calculation of the coefficient of the pionic chiral logarithm âM=M2logM2 is unique and then perform the calculation. As a check we perform the reduction of the known three-flavour result. Our result can be used to perform the extrapolation to the physical pion mass of direct lattice QCD calculations of KâÏÏ at fixed ms or mK2. The underlying arguments are expected to be valid for heavier particles and other processes as well.
