Abstract

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^+\ifmmode±\else\textpm\fi 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_\ensuremath-0.09^+0.09 GeV and M_Z=3.91_\ensuremath-0.09^+0.11 GeV support assigning the X(3872) and Z_c(3900) [or Z_c(3885)] as the 1⁺⁺ and 1^+\ensuremath- diquark-antidiquark type tetraquark states, respectively.
