Photoproduction of exotic baryon resonances

Marek Karliner, Jonathan L. Rosner

Research output: Contribution to journalArticlepeer-review


We point out that the new exotic resonances recently reported by LHCb in the J/ψp channel are excellent candidates for photoproduction off a proton target. This test is crucial to confirming the resonant nature of such states, as opposed to their being kinematical effects. We specialize to an interpretation of the heavier narrow state as a molecule composed of σc and D-*, and estimate its production cross section using vector dominance. The relevant photon energies and fluxes are well within the capabilities of the GlueX and CLAS12 detectors at Thomas Jefferson National Accelerator Facility (JLAB). A corresponding calculation is also performed for photoproduction of an analogous resonance which is predicted to exist in the Υ{hooked}p channel.
