Prediction for the decay width of a charged state near the Ds(D)over-bar*/Ds*(D)over-bar threshold

Very recently the existence of a charged state near the D-s(D) over bar*/D-s*(D) over bar threshold was predicted. This state, that we call Z(cs)(+), would be the strange partner of the recently observed Z(c)(+/-) (3900). Using standard techniques of QCD sum rules, we evaluate the three-point function for the vertices Z(cs)(+)J/psi K+, Z(cs)(+)eta K-c*(+) and Z(cs)(+)D(s)(+)(D) over bar*(0), and we make predictions for the corresponding decay widths in these channels.
