Low energy QCD predictions from non perturbative methods

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

We show that by using lattice results about the euclidean ϱ-propagator, it is possible to give theoretical predictions on the low energy behavior of thee + e −→had. cross section. Furthermore, we present a comparison of perturbative QCD results (plus certain sum rules corrections) with non perturbative results from the lattice in the intermediate energy region.
