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…
