SUMMARY:Gustav Jakobsen - 
DESCRIPTION:Title:Wave Scattering and the Gravitational Compton Amplitude i
 n WQFT\n\n\nAbstract:The gravitational Compton amplitude is an ideal obser
 vable for analyzing quadratic-in-curvature couplings of generic (Kerr) bla
 ck holes in worldline effective field theory (WEFT). The general structure
  of such couplings for Kerr black holes is a major research topic and is\,
  as yet\, unknown. The Compton amplitude describes gravitational waves sca
 ttering off a single black hole and is in this sense a one-body observable
 . This fact makes it ideal for analyzing the WEFT description of black hol
 es without the complication of involving two (or more) black holes. Althou
 gh there is only one black hole\, this process still has a non-trivial loo
 p expansion with several similarities to the two-body impulse problem. Nat
 urally\, this computational challenge is perfectly suited for the worldlin
 e quantum field theory (WQFT) framework. In this talk\, I will discuss rec
 ent work on this topic with Fabian\, Mathias and Kays that we are currentl
 y writing up focusing on the generic and conceptual setup of wave scatteri
 ng in WQFT as well.
