Scalar QED as a toy model for higher-order effects in classical gravitational scattering
Zvi Bern, Juan Pablo Gatica, Enrico Herrmann +2
Quantum Electrodynamics (QED) serves as a useful toy model for classical observables in gravitational two-body systems with reduced complexity due to the linearity of QED. We inves…
The double copy of the multipole expansion
Erick Chacón, Andres Luna, Chris D. White
We consider the classical double copy, that relates solutions of biadjoint scalar, gauge and gravity theories. Using a recently developed twistor expression of this idea, we use we…
Yang-Mills observables: from KMOC to eikonal through EFT
Leonardo de la Cruz, Andres Luna, Trevor Scheopner
We obtain a conservative Hamiltonian describing the interactions of two charged bodies in Yang-Mills through and to all orders in velocity. Our calculation exten…
Quadratic-in-Spin Hamiltonian at from Scattering Amplitudes
Dimitrios Kosmopoulos, Andres Luna
We obtain the quadratic-in-spin terms of the conservative Hamiltonian describing the interactions of a binary of spinning bodies in General Relativity through an…
