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…

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…
