Form factors of gauge theory as correlators of a vertex algebra

Abstract: Form factors are scattering amplitudes in the presence of a local operator. I will explain that, for certain gauge groups, form factors of self-dual Yang-Mills theory (with some additional fields) are the correlators of a vertex algebra. This is joint work with Natalie Paquette, and is closely related to the celestial holography program.
