Discovery potential of hidden charm baryon resonances via photoproduction

In this work, we study the possibility to find and resonances with hidden charm with mass above 4 GeV in the photon-induced production. The cross sections for the photoproductions of hidden charmed baryons are predicted in the effective Lagrangian approach with the vector meson dominance mechanism....

Description
Summary:In this work, we study the possibility to find and resonances with hidden charm with mass above 4 GeV in the photon-induced production. The cross sections for the photoproductions of hidden charmed baryons are predicted in the effective Lagrangian approach with the vector meson dominance mechanism. can be produced directly by photon excitation with total cross section about 1 nb. provides an obvious peak near the threshold for photoproduction, which is expected to be checked by the future high precision experiment at JLab 12 GeV. The results will be helpful in the experimental search for the hidden-charmed baryon resonances in the forthcoming experiments at JLab 12 GeV, such as SoLID, and the proposed electron-ion colliders at FAIR and HIAF.
