Description
High energy collisions at the LHC probe the short distance structure of nature, and then hide the results amongst a pattern of highly energetic jets. The soft interactions of these jets are described by operators involving straight Wilson lines. In this talk I describe a simple setup that can be used to explore these interactions. With a special set of coordinates we map the Wilson lines into static charges on an AdS space. Many of the interesting properties of the anomalous dimensions of multi-Wilson line operators are easily understood from this point of view. For example, a classical energy computation in AdS yields the one-loop anomalous dimension. Motivated by this I introduce a new class of gauges, dubbed conformal gauges, which avoid mixing in R x AdS, and show how they simplify computations at two loops and beyond.
