    "abstract": "We discuss QCD sum rule constraints based on moments of vector meson spectral\ndistributions in the vacuum and in a nuclear medium. Sum rules for the two\nlowest moments of these spectral distributions do not suffer from uncertainties\nrelated to QCD condensates of dimension higher than four. We exemplify these\nrelations for the case of the omega meson and discuss the issue of in-medium\nmass shifts from this viewpoint.",
