Scattering Amplitudes and Conservative Binary Dynamics at without Self-Force Truncation
Zvi Bern, Enrico Herrmann, Radu Roiban +4
We compute the complete potential-graviton contributions to the conservative radial action and scattering angle for two non-spinning bodies in general relativity, accurate through…
Second-order self-force potential-region binary dynamics at in supergravity
Zvi Bern, Enrico Herrmann, Radu Roiban +4
We compute the potential-graviton contributions to the conservative scattering angle of two non-spinning bodies in maximal supergravity at fifth order in Newton's constant, includi…
Unexpected Symmetries of Kerr Black Hole Scattering
Dogan Akpinar, Graham R. Brown, Riccardo Gonzo +1
Motivated by the recent introduction of the Dirac bracket framework to compute spinning observables for the scattering of Kerr black holes, we initiate the study of conserved quant…
Feynman Integral Reduction using Syzygy-Constrained Symbolic Reduction Rules
Sid Smith, Mao Zeng
We present a new algorithm for integration-by-parts (IBP) reduction of Feynman integrals with high powers of numerators or propagators, a demanding computational step in evaluating…
Reinforcement Learning and Metaheuristics for Feynman Integral Reduction
Mao Zeng
We propose new methods for optimizing the integration-by-parts (IBP) reduction of Feynman integrals, an important computational bottleneck in modern perturbative calculations in qu…
First Look at Quartic-in-Spin Binary Dynamics at Third Post-Minkowskian Order
Dogan Akpinar, Fernando Febres Cordero, Manfred Kraus +2
We compute the conservative and radiation-reaction contributions to classical observables in the gravitational scattering between a spinning and a spinless black hole to the fourth…
