Abstract

Hybrid/exotic meson spectroscopy searches at Jefferson Lab require the accurate theoretical description of the production mechanism in peripheral photoproduction. We develop a model for πΔ photoproduction at high energies (5 ≤ E_lab ≤ 16 GeV) that incorporates both the absorbed pion and natural-parity cut contributions. We fit the available observables, providing a good description of the energy and angular dependencies of the experimental data. In conclusion, we also provide predictions for the photon beam asymmetry of charged pions at E_lab = 9 GeV which is expected to be measured by GlueX and CLAS12 experiments in the near future.

Structure of pion photoproduction amplitudes

Journal Article Mathieu, V. ; Nys, J. ; Fernández-Ramírez, C. ; ... - Physical Review. D.

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. Here, we show how the differences in the low-energy side of the sum rules might originate from different quantum number assignments of baryon resonances. We interpret the observed features in the low-energy side of the sum rules with the expectation from Regge theory. Finally, we present a model, in terms of a Regge-pole expansion, that matches the sum rules and the high-energy observables.

Amplitude analysis and the nature of the Z(3900)

Journal Article Pilloni, A. ; Fernández-Ramírez, C. ; Jackura, A. ; ... - Physics Letters B

The microscopic nature of the XYZ states remains an unsettled topic. We show how a thorough amplitude analysis of the data can help constraining models of these states. Specifically, we consider the case of the Z_c(3900) peak and discuss possible scenarios of a QCD state, virtual state, or a kinematical enhancement. Here, we conclude that current data are not precise enough to distinguish between these hypotheses, however, the method we propose, when applied to the forthcoming high-statistics measurements should shed light on the nature of these exotic enhancements.
