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…
Vector Meson Photoproduction with a Linearly Polarized Beam
JPAC Collaboration, V. Mathieu, J. Nys +6
We propose a model based on Regge theory to describe photoproduction of light vector mesons. We fit the SLAC data and make predictions for the energy and momentum transfer dependen…
Analyticity Constraints for Hadron Amplitudes: Going High to Heal Low Energy Issues
JPAC Collaboration, V. Mathieu, J. Nys +7
Analyticity constitutes a rigid constraint on hadron scattering amplitudes. This property is used to relate models in different energy regimes. Using meson photoproduction as a ben…
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…
Toward Complete Pion Nucleon Amplitudes
V. Mathieu, I. V. Danilkin, C. Fernández-Ramírez +4
We compare the low-energy partial wave analyses scattering with a high-energy data via finite energy sum rules. We construct a new set of amplitudes by matching the imaginary…
