On the dependence of the gauge-invariant field-strength correlators in QCD on the shape of the Schwinger string

Abstract

We study, by numerical simulations on a lattice, the dependence of the gauge-invariant two-point field-strength correlators in QCD on the path used to perform the color parallel transport between the two points.
