Vector and Axial-Vector Propagators in the ε-Regime of QCD

Abstract

Using quenched and unquenched chiral perturbation theory we compute vector and axial current two-point functions at finite volume and fixed gauge field topology, in the so-called ε-regime of QCD. A comparison of these results with finite volume lattice calculations allows to determine the parameters of the corresponding chiral Lagrangians.
