Emergence of Calabi-Yau manifolds in high-precision black hole scattering
Mathias Driesse, Gustav Uhre Jakobsen, Albrecht Klemm +5
Using the worldline quantum field theory formalism, we compute the radiation-reacted impulse, scattering angle, radiated energy and recoil of a classical black hole (or neutron sta…

Geometry from Integrability: Multi-Leg Fishnet Integrals in Two Dimensions
Claude Duhr, Albrecht Klemm, Florian Loebbert +2
We generalise the geometric analysis of square fishnet integrals in two dimensions to the case of hexagonal fishnets with three-point vertices. Our results support the conjecture t…

Calabi-Yau periods for black hole scattering in classical general relativity
Albrecht Klemm, Christoph Nega, Benjamin Sauer +1
The high-precision description of black hole scattering in classical general relativity using the post-Minkowskian (PM) expansion requires the evaluation of single-scale Feynman in…
