Abstract
We investigate the charmed baryon production reaction in the effective Lagrangian approach. Besides the -channel and mesons exchanges, the -channel meson exchange is taken into account. For the total cross sections, the and mesons provide minor background contributions, while the state gives a clear peak structure with the magnitude of at center-of-mass energy 4.63 GeV. Based on the results, we suggest that the reaction of can be used to search for the charmoniumlike state, and our predictions may be tested in the future by the facility.
