Photoproduction of within the Regge-plus-resonance model

-meson photoproduction off the proton is studied, which will be useful tool to investigate the charmed-hadron properties. Since many parameters are still unknown in the charmed-hadron photoproduction, we employ the Regge-plus-resonance model, where there are limited number of parameters needed to be adjusted. The background part is modeled within the Regge model with the trajectories being exchanged in the channel or trajectories in the channel. These contributions create the cross sections which are smooth functions of energies. We also introduce the exchange of the hidden-pentaquarks in the channel that create the sharp peak in the cross section predictions.
