Abstract

Quantum-chromodynamic sum rules are derived which are sensitive to resonance contributions and in fact allow one to compute leptonic decay widths and masses of low-lying resonances. The crucial point is the inclusion of power corrections which are related to the vacuum structure of quantum chromodynamics.
