Abstract: (Elsevier)

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 V BL ( x , y ) taken in the limit x → y .

gauge field theory: SU(N)
Wilson loop: light cone
