Gravitational Self-Force and Scattering Amplitudes Workshop

Event description

Recent developments in scattering amplitudes have given new insights into the classical two-body dynamics in the post-Minkowskian expansion (i.e., expansion in Newton's constant), leveraging extremely efficient computational techniques traditionally used for collider physics. At the same time, the gravitational self-force expansion has allowed the gravitational-wave community to develop a description of the two-body dynamics which is fully non-perturbative in the coupling, while being accurate only in the limit of small mass-ratios.

There are exciting prospects in uniting these two complementary approaches, possibly yielding powerful new modeling methods for gravitational-wave astronomy and new insights into the connections between gravity and amplitudes. In the past year there have been notable steps toward this goal, but much more remains to be done to fully benefit from synergies between the two methods. This workshop will bring together experts from both communities to establish new collaborations, with the following topics to be discussed:

  • recovering self-force through resummation of PM results;
  • comparison between self-force and analytical post-Newtonian/post-Minkowskian results;
  • Kerr black holes from amplitudes and point particles;
  • double copy structures in classical gravity and black hole perturbation theory.
