Leading Nonlinear Tidal Effects and Scattering Amplitudes
Zvi Bern, Julio Parra-Martinez, Radu Roiban +2
We present the two-body Hamiltonian and associated eikonal phase, to leading post-Minkowskian order, for infinitely many tidal deformations described by operators with arbitrary po…
Structure of two-loop SMEFT anomalous dimensions via on-shell methods
Zvi Bern, Julio Parra-Martinez, Eric Sawyer
We describe on-shell methods for computing one- and two-loop anomalous dimensions in the context of effective field theories containing higher-dimension operators. We also summariz…
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…
