Query: Non-leptonic weak decays and final state interactions in lattice QCD   We show that, under a reasonable "smoothness" hypothesis, it is possible to
extract informations on the amplitude and phase of two-body non-leptonic weak
decay matrix elements from the study of Euclidean correlation functions in
lattice QCD.
