The decay width of the $$Z_c(3900)$$ Zc(3900) as an axialvector tetraquark state in solid quark–hadron duality
Abstract In this article, we tentatively assign the $$Z_c^\pm (3900)$$ Zc±(3900) to be the diquark–antidiquark type axialvector tetraquark state, study the hadronic coupling constants $$G_{Z_cJ/\psi \pi }, G_{Z_c\eta _c\rho }, G_{Z_cD \bar{D}^{*}}$$ GZcJ/ψπ,GZcηcρ,GZcDD¯∗ with the QCD sum rules in d...
