Radiative Classical Gravitational Observables at from Scattering Amplitudes
Enrico Herrmann, Julio Parra-Martinez, Michael S. Ruf +1
We compute classical gravitational observables for the scattering of two spinless black holes in general relativity and supergravity in the formalism of Kosower,…
Gravitational Bremsstrahlung from Reverse Unitarity
Enrico Herrmann, Julio Parra-Martinez, Michael S. Ruf +1
We compute the total radiated momentum carried by gravitational waves during the scattering of two spinless black holes at the lowest order in Newton's constant, ,…
Scattering Amplitudes and Conservative Binary Dynamics at
Zvi Bern, Julio Parra-Martinez, Radu Roiban +4
Using scattering amplitudes, we obtain the potential contributions to conservative binary dynamics in general relativity at fourth post-Minkowskian order, . As in pr…
Extremal black hole scattering at O(G^3): graviton dominance, eikonal exponentiation, and differential equations
Julio Parra-Martinez, Michael S. Ruf, Mao Zeng
We use supergravity as a toy model for understanding the dynamics of black hole binary systems via the scattering amplitudes approach. We compute the conservative pa…
Universality in the classical limit of massless gravitational scattering
Zvi Bern, Harald Ita, Julio Parra-Martinez +1
We demonstrate the universality of the gravitational classical deflection angle of massless particles through O(G^3) by studying the high-energy limit of full two-loop four-gravito…
Quantum effective action for degenerate vector field theories
Michael S. Ruf, Christian F. Steinwachs
We calculate the divergent part of the one-loop effective action in curved spacetime for a particular class of second-order vector field operators with a degenerate principal part.…
