Classical Gravitational Scattering from the Ultraviolet and the Absence of Calabi-Yau Integrals in the Conservative Sector at

Zvi Bern, Avery Jackman, Gareth Mansfield +1

We explain why Calabi-Yau and complete elliptic integrals do not contribute to conservative observables at fifth post-Minkowskian order, despite appearing in intermediate steps. At…

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…

Observables and Unconstrained Spin Tensor Dynamics in General Relativity from Scattering Amplitudes

Mark Alaverdian, Zvi Bern, Dimitrios Kosmopoulos +4

In a previous Letter, we showed that physical scattering observables for compact spinning objects in general relativity can depend on additional degrees of freedom in the spin tens…

Amplitudes, Supersymmetric Black Hole Scattering at , and Loop Integration

Zvi Bern, Enrico Herrmann, Radu Roiban +4

We compute the potential-graviton contribution to the scattering amplitude, the radial action, and the scattering angle of two extremal black holes in N = 8 supergravity at the fif…

Conservative Spin Magnitude Change in Orbital Evolution in General Relativity

Mark Alaverdian, Zvi Bern, Dimitrios Kosmopoulos +4

We show that physical scattering observables for compact spinning objects in general relativity can depend on additional degrees of freedom in the spin tensor beyond those describe…
