S-matrix informed neural networks for amplitude analysis
Wyatt A. Smith, Arkaitz Rodas, Marius D. Thomas +5
Reconstructing scattering amplitudes from finite, noisy, and mutually inconsistent measurements is an ill-posed inverse problem common to many reactions relevant to particle physic…
Neuro-dispersive extractions of light-meson resonances
Wyatt A. Smith, Arkaitz Rodas, Marius D. Thomas +5
We present the first dispersive extraction of resonant poles from analytically continued neural networks. We use S-matrix informed neural networks (SINNs) trained to respect unitar…
First determination of vector and tensor couplings from polarized photoproduction
Vanamali Shastry, Łukasz Bibrzycki, Vincent Mathieu +7
The couplings between hadrons encode the dynamics of quantum chromodynamics. While many couplings can be calculated from decay widths, in some cases the decays are kinematically fo…
Mechanisms of high energy polarized photoproduction of
Vanamali Shastry, Łukasz Bibrzycki, Vincent Mathieu +7
We present an amplitude analysis of high-energy polarized photoproduction of within a Regge exchange framework. A Regge amplitude model incorporating , , , a…
On the Equivalence of Three-Particle Scattering Formalisms
A. W. Jackura, S. M. Dawid, C. Fernández-Ramírez +5
In recent years, different on-shell scattering formalisms have been proposed to be applied to both lattice QCD and infinite volume scattering processes. W…
Structure of Pion Photoproduction Amplitudes
V. Mathieu, J. Nys, C. Fernandez-Ramirez +5
We derive and apply the finite energy sum rules to pion photoproduction. We evaluate the low energy part of the sum rules using several state-of-the-art models. We show how the dif…
Global analysis of charge exchange meson production at high energies
JPAC Collaboration, J. Nys, A. N. Hiller Blin +7
Many experiments that are conducted to study the hadron spectrum rely on peripheral resonance production. Hereby, the rapidity gap allows the process to be viewed as an independent…
Charmonium spectrum with a Dirac potential model in the momentum space
D. Molina, M. De Sanctis, C. Fernandez-Ramirez
We study the charmonium spectrum using a complete one gluon exchange approach based on a phenomenological relativistic potential model with Dirac spinors in momentum spa…
Finite-Energy Sum Rules in Eta Photoproduction off the Nucleon
JPAC Collaboration, J. Nys, V. Mathieu +8
The reaction is studied in the high-energy regime (with photon lab energies GeV) using information from the resonance region through the use of…
Three-body Final State Interaction in
Peng Guo, Igor V. Danilkin, Diane Schott +3
We present an unitary dispersive model for the decay process based upon the Khuri-Treiman equations which are solved by means of the Pasquier inversion method. The descr…
