摘要In this article, we distinguish the charge conjunctions of the interpolating currents, calculate the contributions of the vacuum condensates up to dimension 10 in a consistent way in the operator product expansion, study the masses and pole residues of the J(PC) = 1(++/-) hidden charmed tetraquark states with the QCD sum rules, and explore the energy-scale dependence in detail for the first time. The predictions M-X = 3.87(- 0.09)(+0.09) GeV and M-Z 3.91 (+0.11) (-0.09) GeV support assigning the X(3872) and Z(c)(3900) [or Z(c)(3885)] as the 1(++) and 1(+-) diquark-antidiquark type tetraquark states, respectively.
