On light-like Wilson loops
Abstract
The renormalization of the vacuum averaged Wilson loop evaluated along the path containing the light-like segments is performed. It is found that the renormalized Wilson loop obeys an evolution equation well known in perturbative QCD. The kernel of this equation coincides with the Brodsky-Lepage evolution kernel VBL ( x, y) taken in the limit x → y.
