Description
Wilson lines are a prototypical example of defect in quantum field theory. After
reviewing the superconformal case - in which the one-dimensional defect CFT that
they define is particularly interesting - I will discuss some analytic tools that may
prove useful in this context, but are developed for generic 1d CFTs. Among them, a
representation of the four-point correlator as a Mellin amplitude and via a recently
derived dispersion relation.
