Abstract
We present our calculation of the correlator [T{VsVsdagger}] between two ex ternal vector-currents with the quantum-numbers of a charged kaon. The reno rmalized expression to O(p(6)) in SU(3) x SU(3) standard chiral perturbatio n theory is finite and scale-independent. The result is used to determine, via an IMFESR, the phenomenologically relevant finite O(p(6))-counterterm c ombination Q(V) in a way which is not sensitive to isospin breaking.
