With an effective Lagrangian approach and the isobar model, we explore the discovery potential of the production via scattering. Moreover, the background from the reaction through s-channel and u-channel by exchanging a nucleon pole is also considered. It is found that the center-of-mass energy is the best energy window for searching the resonance, where the signal can be easily distinguished from background. The relevant calculations will be conductive to search for the resonance in further experiment and have a more comprehensive understanding of hidden charm baryons.
