Description

Correlators of Wilson lines, possibly accompanied by local fields, play a
remarkably important role in QCD and general gauge theories. After reviewing some of their properties, in particular concerning their exponentiation, I will discuss some recent results, including a proposal for a useful organisation of the pertubative exponent, and the determination of the colour structures contributing to the soft anomalous dimension matrix at the four-loop level.
