Abstract
We study the decay properties of the recently observed charmonium-like structure Zc(3900). Using QCD sum rules we evaluate the three-point function and extract the coupling constants of the , and vertices and the corresponding decay widths in these channels. The results obtained are in good agreement with the experimental data and support to the tetraquark interpretation of this state.
