Abstract / Bemerkung
By subtracting from a recent lattice measurement of the thermalvector-current correlator the known 5-loop vacuum contribution, we demonstratethat the remainder is small and shows no visible short-distance divergence. Itcan therefore in principle be subjected to model-independent analyticcontinuation. Testing a particular implementation, we obtain estimates for theflavour-diffusion coefficient (2 pi T D \gsim 0.8) and electrical conductivitywhich are significantly smaller than previous results. Although systematicerrors remain beyond control at present, some aspects of our approach could beof a wider applicability.
