Photoproduction of the charged charmoniumlike Zc+(4200 )

In this work, inspired by the observation of charmoniumlike Z_c⁺(4200 ), we study the photoproduction of charged charmoniumlike Z_c⁺(4200 ) with an effective Lagrangian approach and the Regge trajectories model. The numerical results indicate that the Reggeized treatment can lead to a lower total cross section of the Z_c⁺(4200 ) photoproduction and the peak position of the cross section was moved to the higher energy point when the Reggeized treatment was added. Moreover, by using the data from the COMPASS experiment and presented theoretical predictions, an upper limit of the decay width of Z_c(4200 )→J /ψ π is estimated. The relevant results not only shed light on the further experiment of searching for the charmoniumlike Z_c(4200 ) state via meson photoproduction, but also provide valuable information for having a better comprehension of the nature of a charmoniumlike Z_c(4200 ) state.
