Predicition for the decay width of a charged state near the \(D_s\bar{D}^/D^_s\bar{D}\) threshold

Very recently it was predicted the existence of a charged state near the \(D_s\bar{D}^*/D^*_s\bar{D}\) threshold. This state, that we call \(Z_{cs}^+\), would be the strange partner of the recently observed \(Z_c^\pm(3900)\). Using standard techniques of QCD sum rules, we evaluate the three-point fu...

Description
Summary:Very recently it was predicted the existence of a charged state near the \(D_s\bar{D}^*/D^*_s\bar{D}\) threshold. This state, that we call \(Z_{cs}^+\), would be the strange partner of the recently observed \(Z_c^\pm(3900)\). Using standard techniques of QCD sum rules, we evaluate the three-point function for the vertices \(Z_{cs}^+ \, J/\psi \, K^+\), \(Z_{cs}^+ \, \eta_c \, K^{*+}\) and \(Z_{cs}^+ \, D_s^+\bar{D}^{*0}\) and we make predictions for the corresponding decay widths in these channels.
