Gluon & graviton scattering in the de Sitter static patch

If you have a question about this talk, please contact Dr Dong-Gang Wang .

I report the status of a research program to compute scattering between the past and future horizons of an observer in de Sitter space. I focus on Yang-Mills theory and the self-dual sector of General Relativity, both at tree level. Helicity plays the same key role as in the asymptotically flat S-matrix, in contrast with the more standard de Sitter problem of inflationary correlators. Along the way, I construct a lightcone ansatz for self-dual gravity solutions in the Poincare patch, using Kirill Krasnov’s wondrous chiral formulation of GR.
