Classical gravitational scattering with a massive scalar mediator

Birgitta Biendarra, Kays Haddad, Jan Plefka

We consider the classical scattering of two gravitating compact objects in the presence of a massive scalar mediator, providing a simple model of exotic phenomena. Through dimensio…

Conservative Black Hole Scattering at Fifth Post-Minkowskian and Second Self-Force Order

Mathias Driesse, Gustav Uhre Jakobsen, Gustav Mogull +4

Using the worldline quantum field theory formalism, we compute conservative contributions to the scattering angle and impulse for classical black hole scattering at fifth post-Mink…

Unitarity and the On-Shell Action of Worldline Quantum Field Theory

Kays Haddad, Gustav Uhre Jakobsen, Gustav Mogull +1

We develop the on-shell action formalism within Worldline Quantum Field Theory (WQFT) to describe scattering of spinning compact bodies in General Relativity in the post-Minkowskia…

Spinning the Probe in Kerr with WQFT

Jitze Hoogeveen, Gustav Uhre Jakobsen, Jan Plefka

We investigate the gravitational scattering of a spinning probe mass in a Kerr background using the worldline quantum field theory (WQFT) approach. This corresponds to the leading…

Radiated Angular Momentum from Spinning Black Hole Scattering Trajectories

Gustav Mogull, Jan Plefka, Kathrin Stoldt

Using the worldline quantum field theory approach we derive solutions to the equations of motion for spinning massive bodies up to quadratic order in spins. At leading post-Minkows…

Spinning bodies in general relativity from bosonic worldline oscillators

Kays Haddad, Gustav Uhre Jakobsen, Gustav Mogull +1

Worldline quantum field theory (WQFT) has proven itself a powerful tool for classical two-body scattering calculations in general relativity. In this paper we develop a new worldli…
