Expressing the three-particle finite-volume spectrum in terms of the three-to-three scattering amplitude [PDF]
, 2015 In this article we complete our formalism relating the finite-volume energy spectrum of a scalar quantum field theory to the three-to-three scattering amplitude, ${\cal M}_3$.

Tidal effects for spinning particles
Journal of High Energy Physics, 2021 Expanding on the recent derivation of tidal actions for scalar particles, we present here the action for a tidally deformed spin-1/2 particle. Focusing on operators containing two powers of the Weyl tensor, we combine the Hilbert series with an on-shell ...

Scattering amplitude and bosonization duality in general Chern-Simons vector models [PDF]
, 2016 A bstractWe present the exact large N calculus of four point functions in general Chern-Simons bosonic and fermionic vector models. Applying the LSZ formula to the four point function we determine the two body scattering amplitudes in these theories ...

Scattering Amplitudes and the Conservative Hamiltonian for Binary Systems at Third Post-Minkowskian Order. [PDF]
Physical Review Letters, 2019 We present the amplitude for classical scattering of gravitationally interacting massive scalars at third post-Minkowskian order. Our approach harnesses powerful tools from the modern amplitudes program such as generalized unitarity and the double-copy ...

Eikonal fit to $pp$ and $\bar{p}p$ scattering and the edge in the scattering amplitude [PDF]
, 2015 We make a detailed eikonal fit to current data on the total and elastic scattering cross sections, the ratios $\rho$ of the real to the imaginary parts of the forward elastic scattering amplitudes, and the logarithmic slopes $B$ of the differential cross

Protostring scattering amplitudes [PDF]
Physical Review D, 2016 We calculate some tree level scattering amplitudes for a generalization of the protostring, which is a novel string model implied by the simplest string bit models. These bit models produce a lightcone worldsheet which supports $s$ integer moded Grassmann fields.

Wave-scattering from a gently curved surface
Physics Letters B, 2016 We study wave scattering from a gently curved surface. We show that the recursive relations, implied by shift invariance, among the coefficients of the perturbative series for the scattering amplitude allow to perform an infinite resummation of the ...

The High Energy Behavior of Mellin Amplitudes [PDF]
, 2019 In any consistent massive quantum field theory there are well-known bounds on scattering amplitudes at high energies. In conformal field theory there is no scattering amplitude, but the Mellin amplitude is a well-defined object analogous to the ...
