Description
Calculations of the scattering angle in hyperbolic black hole encounters have been of recent cross-disciplinary interest, driven by its potential to advance post-Minkowskian theory and the effective-one-body model of binary dynamics. In this talk I will consider the self-force approach to modelling black hole scattering, starting with a general introduction to self-force theory and the motivation for self-force scattering. I will then introduce the scalar-field toy model that has been widely used in recent self-force scattering research, and describe our efforts to develop a frequency-domain numerical method to calculate the scalar-field self-force during hyperbolic encounters. I will end the talk by discussing some ongoing areas of work in self-force scattering, in particular the use of self-force results to resum analytical post-Minkowskian series, and work to obtain analytical results for the self-force at early and late times along scattering orbits.
