- Abstract: We identify the recently observed charmonium-like structure Z ± c (3900) as the charged partner of the X(3872) state. Using standard techniques of QCD sum rules, we evaluate the three-point function and extract the coupling constants of the Z + c J/ψ π+, Z + c ηc ρ + and Z + c D+D¯∗0 vertices and the corresponding decay widths in these channels. The good agreement with the experimental data gives support to the tetraquark picture of this state.
