Event details
Correlators of Wilson line operators are known to exponentiate in the non-abelian gauge theory and their logarithms can be arranged in terms of a collection of Feynman diagrams known as webs. Webs are a set of diagrams that mix among themselves by a mixing matrix known. After reviewing the algorithm to generate the mixing matrices and their properties, I will discuss some recent results, a proposal for organizing webs at higher perturbative orders, a new way of constructing the mixing matrices, and the colour structures contributing to the soft anomalous dimension at the four-loop level.
