Description
In this talk I will discuss our recent calculation of the conservative fifth post-Minkowskian (5PM) scattering angle, at first order in self-force, using the Worldline Quantum Field Theory (WQFT) formalism. This challenging calculation involved performing four-loop Feynman integrals, and surprisingly resulted in a total absence of the elliptic functions present at 4PM order — the entire result is expressed on a basis of weight-3 multiple polylogarithms (MPLs).
