Abstract
I will discuss the perturbative cusp and closed polygons of Wilson lines for massless gauge theories in coordinate space. A direct perturbative prescription for the logarithm of the cusp and related cross sections treated in eikonal approximation is provided by web diagrams. I will describe the properties of these web diagrams in coordinate space, and talk about their singularities, renormalization, and geometric interpretation.
