Global Bases for Nonplanar Loop Integrands, Generalized Unitarity, and the Double Copy to All Loop Orders
Zvi Bern, Enrico Herrmann, Radu Roiban +2
We introduce a constructive method for defining a global loop-integrand basis for scattering amplitudes, encompassing both planar and nonplanar contributions. Our approach utilizes…
Spinning Black Hole Scattering at : Casimir Terms, Radial Action and Hidden Symmetry
Dogan Akpinar, Fernando Febres Cordero, Manfred Kraus +2
We resolve subtleties in calculating the post-Minkowskian dynamics of binary systems, as a spin expansion, from massive scattering amplitudes of fixed finite spin. In particular, t…
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…
