What is the right formalism to search for resonances?
JPAC Collaboration, M. Mikhasenko, A. Pilloni +8
Hadron decay chains constitute one of the main sources of information on the QCD spectrum. We discuss the differences between several partial wave analysis formalisms used in the l…
Features of Photoproduction at High Energies
J. Nys, V. Mathieu, C. Fernández-Ramírez +7
Hybrid/exotic meson spectroscopy searches at Jefferson Lab require the accurate theoretical description of the production mechanism in peripheral photoproduction. We develop a mode…
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…
New analysis of tensor resonances measured at the COMPASS experiment
A. Jackura, C. Fernandez-Ramirez, M. Mikhasenko +232
We present a new amplitude analysis of the -wave in measured by COMPASS. Employing an analytical model based on the principles of the relativistic -mat…
On the and Photoproduction Beam Asymmetry at High Energies
V. Mathieu, J. Nys, C. Fernández-Ramírez +5
We show that, in the Regge limit, beam asymmetries in and photoproduction are sensitive to hidden strangeness components. Under reasonable assumptions about the couplings…
