Non-renormalization and operator mixing via on-shell methods
Zvi Bern, Julio Parra-Martinez, Eric Sawyer
Using on-shell methods, we present a new perturbative non-renormalization theorem for operator mixing in massless four-dimensional quantum field theories. By examining how unitarit…
The Duality Between Color and Kinematics and its Applications
Zvi Bern, John Joseph Carrasco, Marco Chiodaroli +2
This review describes the duality between color and kinematics and its applications, with the aim of gaining a deeper understanding of the perturbative structure of gauge and gravi…
Black Hole Binary Dynamics from the Double Copy and Effective Theory
Zvi Bern, Clifford Cheung, Radu Roiban +3
We describe a systematic framework for computing the conservative potential of a compact binary system using modern tools from scattering amplitudes and effective field theory. Our…
Two-loop n-point anomalous amplitudes in N=4 supergravity
Zvi Bern, David Kosower, Julio Parra-Martinez
We compute the anomalous two-loop four-point amplitudes in N=4 pure supergravity, using unitarity and the double-copy construction. We also present all terms determined by four-dim…
Scattering Amplitudes and the Conservative Hamiltonian for Binary Systems at Third Post-Minkowskian Order
Zvi Bern, Clifford Cheung, Radu Roiban +3
We present the amplitude for classical scattering of gravitationally interacting massive scalars at third post-Minkowskian order. Our approach harnesses powerful tools from the mod…
