Gravitational Sommerfeld Effects: Formalism, Renormalization, and Perturbation to
Chih-Hao Chang, Chia-Hsien Shen, Zihan Zhou
In the effective field theory (EFT) description of binary inspirals, the radiated gravitational waveform receives universal corrections from the curved background, the so-called ``…
Fermion Geometry and the Renormalization of the Standard Model Effective Field Theory
Benoît Assi, Andreas Helset, Aneesh V. Manohar +2
The geometry of field space governs on-shell scattering amplitudes. We formulate a geometric description of effective field theories which extends previous results for scalars and…
Comparison of post-Minkowskian and self-force expansions: Scattering in a scalar charge toy model
Leor Barack, Zvi Bern, Enrico Herrmann +8
We compare numerical self-force results and analytical fourth-order post-Minkowskian (PM) calculations for hyperbolic-type scattering of a point-like particle carrying a scalar cha…
Inflationary Adler Conditions
Daniel Green, Yiwen Huang, Chia-Hsien Shen
We derive a new soft theorem that corresponds to the spontaneous breaking of Lorentz boosts. This is motivated by the dynamics of inflation in the sub-horizon (flat-space) limit, w…
Radiated Angular Momentum and Dissipative Effects in Classical Scattering
Aneesh V. Manohar, Alexander K. Ridgway, Chia-Hsien Shen
We present a new formula for the angular momentum carried away by gravitational radiation in classical scattering. This formula, combined with the known expression for the…
Scattering Amplitudes, the Tail Effect, and Conservative Binary Dynamics at
Zvi Bern, Julio Parra-Martinez, Radu Roiban +4
We complete the calculation of conservative two-body scattering dynamics at fourth post-Minkowskian order, i.e. and all orders in velocity, including radiative contributio…

Zvi Bern, Julio Parra-Martinez, Radu Roiban +4
Using scattering amplitudes, we obtain the potential contributions to conservative binary dynamics in general relativity at fourth post-Minkowskian order, . As in pr…
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…
Spinning Black Hole Binary Dynamics, Scattering Amplitudes and Effective Field Theory
Zvi Bern, Andres Luna, Radu Roiban +2
We describe a systematic framework for finding the conservative potential of compact binary systems with spin based on scattering amplitudes of particles of arbitrary spin and effe…
Hidden Conformal Invariance of Scalar Effective Field Theories
Clifford Cheung, James Mangan, Chia-Hsien Shen
We argue that conformal invariance is a common thread linking several scalar effective field theories that appear in the double copy and scattering equations. For a derivatively co…

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…

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…
Dual Conformal Structure Beyond the Planar Limit
Zvi Bern, Michael Enciso, Chia-Hsien Shen +1
The planar scattering amplitudes of super-Yang--Mills theory display symmetries and structures which underlie their relatively simple analytic properties such as…
Gravitational Radiation from Color-Kinematics Duality
Chia-Hsien Shen
We perturbatively calculate classical radiation in Yang-Mills theory and dilaton gravity, to next-to-leading order in couplings. The radiation is sourced by the scattering of two r…

We present a bottom-up construction of vector effective field theories using the infrared structure of scattering amplitudes. Our results employ two distinct probes of soft kinemat…
Pions as Gluons in Higher Dimensions
Clifford Cheung, Grant N. Remmen, Chia-Hsien Shen +1
We derive the nonlinear sigma model as a peculiar dimensional reduction of Yang-Mills theory. In this framework, pions are reformulated as higher-dimensional gluons arranged in a k…
Unifying Relations for Scattering Amplitudes

We derive new amplitudes relations revealing a hidden unity among wide-ranging theories in arbitrary spacetime dimensions. Our results rely on a set of Lorentz invariant differenti…
Symmetry and Action for Flavor-Kinematics Duality
Clifford Cheung, Chia-Hsien Shen
We propose a new representation of the nonlinear sigma model that exhibits a manifest duality between flavor and kinematics. The fields couple exclusively through cubic Feynman ver…
A Periodic Table of Effective Field Theories
Clifford Cheung, Karol Kampf, Jiri Novotny +2
We systematically explore the space of scalar effective field theories (EFTs) consistent with a Lorentz invariant and local S-matrix. To do so we define an EFT classification based…
On-Shell Recursion Relations for Effective Field Theories
Clifford Cheung, Karol Kampf, Jiri Novotny +2
We derive the first ever on-shell recursion relations for amplitudes in effective field theories. Based solely on factorization and the soft behavior of amplitudes, these recursion…
Non-renormalization Theorems without Supersymmetry
Clifford Cheung, Chia-Hsien Shen
We derive a new class of one-loop non-renormalization theorems that strongly constrain the running of higher dimension operators in a general four-dimensional quantum field theory.…
Simple Recursion Relations for General Field Theories
Clifford Cheung, Chia-Hsien Shen, Jaroslav Trnka
On-shell methods offer an alternative definition of quantum field theory at tree-level, replacing Feynman diagrams with recursion relations and interaction vertices with a handful…
