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 Observation of an Exotic Reggeon
G. D. Alexeev, M. G. Alexeev, C. Alice +180
We present new \compass high-statistics measurements of the peripheral production of and pairs in the reactions . For the first t…
Production Effects and Final-state Interactions in
D. Winney, S. Gonzàlez-Solís, M. Mikhasenko +8
We investigate the signal channel of in the -wave. This channel has recently been analyzed by the COMPASS collaboration using t…
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…
Finite-volume analysis of the -dibaryon including left-hand-cut effects
Arkaitz Rodas, Lin Qiu, César Fernández-Ramírez +4
We implement the finite-volume representation to study two-baryon interactions from lattice QCD data. We include the left-hand cut induced by one-pion exchange in this formal…
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…
High-energy photoproduction and the nature of exotic waves
Gloria Montaña, Vincent Mathieu, Vanamali Shastry +9
The observation of hybrid mesons in photoproduction experiments can provide essential insight into the inner workings of quantum chromodynamics in the strong coupling regime. In pa…
Towards a unified description of hadron scattering at all energies
Dominik Stamen, Daniel Winney, Arkaitz Rodas +5
The construction of general amplitudes satisfying symmetries and -matrix constraints has been the primary tool in studying the spectrum of hadrons for over half a century. In th…
Coulomb confinement in the Hamiltonian limit
Sebastian M. Dawid, Wyatt A. Smith, Arkaitz Rodas +4
The Gribov--Zwanziger scenario attributes the phenomenon of confinement to the instantaneous interaction term in the QCD Hamiltonian in the Coulomb gauge. For a static quark-antiqu…
Revisiting gauge invariance and Reggeization of pion exchange
Gloria Montana, Daniel Winney, Lukasz Bibrzycki +10
The Reggeized pion is expected to provide the main contribution to the forward cross section in light meson photoproduction reactions with charge exchange at high energies. We disc…
Studying photoproduction beyond Pomeron exchange
Łukasz Bibrzycki, Nadine Hammoud, Vincent Mathieu +10
Forward photoproduction of pairs with invariant mass of the order of MeV is traditionally understood to be produced via Pomeron exchange. Based on a detailed…
Nonperturbative aspects of the electromagnetic pion form factor at high energies
Joint Physics Analysis Center, :, K. Quirion +10
The structure of hadronic form factors at high energies and their deviations from perturbative quantum chromodynamics provide insight on nonperturbative dynamics. Using an approach…
XYZ spectroscopy at electron-hadron facilities III: Semi-inclusive processes with vector exchanges
Joint Physics Analysis Center Collaboration, D. Winney, A. Pilloni +10
Inclusive production processes will be important for the first observations of states at new generation electron-hadron colliders, as they generally benefit from larger cross…
