High Energy Physics - Phenomenology 2007-05-23 v3

Abstract

The leading perturbative contributions into the two-point gauge-invariant correlator Tr<gF(x)U(x,0)U(0,y)F(y)U(y,0)U(0,x)>Tr<gF(x)U(x,0)U(0,y)F(y)U(y,0)U(0,x)> are calculated at the one-loop order. It is shown, that nonlocal condensate is nonzero at this order. The relation with the renormalization properties of Wilson loops is discussed.
