Variation on finite energy sum rules: Vacuum matrix elements

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

New finite energy sum rules for light quark systems are derived in QCD, which express nonperturbative vacuum matrix elements of a given dimension in terms of the spectral function and its derivatives. A phenomelogical definition of nonperturbative effects is proposed.
