Abstract
Conformal covariance is shown to determine renormalization properties of composite operators in QCD and in the ϕ 6 3-model at the one-loop level. Its relevance to higher-order (renormalization group improved) perturbative calculations in the short-distance limit is also discussed. Light cone operator product expansions and spectral representations for wavefunctions in QCD are derived.
