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…
First steps towards gauge-independent vortex identification through machine learning
Wyatt A. Smith, César Fernández-Ramírez, Jeff Greensite +1
As a first step towards machine identification of confining objects in thermalized lattice gauge configurations, we present our 2dVoId model for center vortex identification on pur…
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…
Kaluza-Klein reduction on a maximally non-Riemannian space is moduli-free
Kyoungho Cho, Kevin Morand, Jeong-Hyuck Park
We propose a novel Kaluza-Klein scheme which assumes the internal space to be maximally non-Riemannian, meaning that no Riemannian metric can be defined for any subspace. Its descr…
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…
Model Selection for Pion Photoproduction
J. Landay, M. Döring, C. Fernández-Ramírez +2
Partial-wave analysis of meson and photon-induced reactions is needed to enable the comparison of many theoretical approaches to data. In both energy-dependent and independent para…
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…
Spectral-statistics properties of the experimental and theoretical light meson spectra
L. Munoz, C. Fernandez-Ramirez, A. Relano +1
We present a robust analysis of the spectral fluctuations exhibited by the light meson spectrum. This analysis provides information about the degree of chaos in light mesons and ma…
The unexpected role of D waves in low-energy neutral pion photoproduction
C. Fernandez-Ramirez
It has been commonly assumed that low-energy neutral pion photoproduction from the proton can be described accounting only for S and P waves, and that higher partial waves are irre…
