Photoproduction of the charmonium-like state Zc(4200) and the charmed baryon Λc∗ (2940) is investigated with an effective Lagrangian approach and the Regge trajectories applying to the COMPASS experiment. Combining the experimental data from COMPASS and our theoretical model we estimate the upper limit of Γ_Zc(4200)→ J/ψπ to be of about 37 MeV. Moreover, the possibility to produce Λc∗ (2940) at COMPASS is discussed. It seems one can try to search for this hadron in the missing mass spectrum since the t-channel is dominating for the Λc∗ (2940) photoproduction.
