QG group meeting: Yang-Mills scattering in de Sitter

This is the weekly QG group meeting.
Speaker: Yasha Neiman.
Title: "Yang-Mills scattering in de Sitter space".

I will discuss our current work with Mirian on Yang-Mills scattering in the de Sitter static patch. I will describe some general techniques for thinking about conformal theories in the static patch, which reduces the question to a partially off-shell calculation in Minkowski space. I will then present results for N^{-1}MHV and MHV scattering in Yang-Mills theory, using self-dual field solutions and (a close relative of) BCFW recursion.
