Abstract

We present the inconsistencies which arise in quenched QCD in ΔI=1/2\Delta I=1/2 non-leptonic kaon decays using chiral perturbation theory (ChPT) to one loop. In particular we discuss how the lack of unitarity of the quenched theory invalidates the usual methods for the extraction of matrix elements from correlation functions.
