Discovery potential of hidden charm baryon resonances via photoproduction

In this work, we study the possibility to find N-c (c) over bar* and Lambda(c (c) over bar)* 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. N*(4412) can be produced directly by photon excitation with total cross section about 1 nb. N*(4412) provides an obvious peak near the threshold for J/psi 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.
