The gravitational Compton amplitude at third post-Minkowskian order
N. Emil J. Bjerrum-Bohr, Gang Chen, Carl Jordan Eriksen +1
We employ a single worldline effective field theory in a Schwarzschild--Tangherlini background to compute the gravitational Compton amplitude up to third post-Minkowskian order. By…

The gravitational Compton amplitude from flat and curved spacetimes at second post-Minkowskian order
N. Emil J. Bjerrum-Bohr, Gang Chen, Carl Jordan Eriksen +1
We utilize various computational techniques in flat and curved backgrounds to calculate the classical gravitational Compton amplitude up to the second post-Minkowskian order. Our n…

Mining the Geodesic Equation for Scattering Data
Clifford Cheung, Nabha Shah, Mikhail P. Solon
The geodesic equation encodes test-particle dynamics at arbitrary gravitational coupling, hence retaining all orders in the post-Minkowskian (PM) expansion. Here we explore what ge…
