Discovery potential of hidden charm baryon resonances via photoproduction

Abstract

In this work, we study the possibility to find $N_{c\bar{c}}^{\ast }$ and ${\Lambda }_{c\bar{c}}^{\ast }$ 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. The $N^{\ast }(4412)$ can be produced directly by photon excitation with total cross section about 1 nb. The $N^{\ast }(4412)$ provides a obvious peak near threshold for $J/\psi$ photoproduction, which is promising to be checked by the future high precision experiment at JLab 12 GeV. The results will be helpful to the experimental search for the hidden-charmed baryon resonances in the coming experiment at JLab 12 GeV, such as SoLID, and the proposed electron-ion colliders at FAIR and HIAF.
