An improved partial-wave projection of the one-particle exchange in relativistic three-body scattering
Nicholas C. Chambers, Andrew W. Jackura
A critical component of relativistic three-body scattering amplitudes is the one-particle exchange (OPE) process, wherein a single particle is exchanged between incoming and outgoi…
Resolving the structure of bound states using lattice quantum field theories
Joseph Moscoso, Felipe G. Ortega-Gama, Raúl A. Briceño +3
This work presents the first lattice calculation of a two-to-two particle matrix element of a local current. This exploratory calculation is performed using a leading-order pionles…
Isotensor scattering with a resonant subsystem from QCD
Raúl A. Briceño, Maxwell T. Hansen, Andrew W. Jackura +2
This work presents a lattice quantum chromodynamics (QCD) determination of scattering amplitudes for the isospin-2 channel with angular momentum and parity . The…
Symmetrizing relativistic three-body partial wave amplitudes
Andrew W. Jackura, Nicholas C. Chambers, Raúl A. Briceño
S matrix principles and symmetries impose constraints on three-particle scattering amplitudes, which can be formulated as a class of integral equations for their partial wave proje…
Extracting scattering amplitudes for arbitrary two-particle systems with one-particle left-hand cuts via lattice QCD
André Baião Raposo, Raúl A Briceño, Maxwell T Hansen +1
We derive a general formalism that relates the spectrum of two-particle systems in a finite volume to physical scattering amplitudes, taking into account the presence of any left-h…
Finite-volume quantization condition from the representation
Sebastian M. Dawid, Andrew W. Jackura, Adam P. Szczepaniak
We propose a new model-independent method for determining hadronic resonances from lattice QCD. The formalism is derived from the general principles of unitarity and analyticity, a…
