Abstract

In this article, we take the X(4140) as the diquark-antidiquark type cscs tetraquark state with J^PC=1⁺⁺, and study the mass and pole residue with the QCD sum rules in details by constructing two types interpolating currents. The numerical results M_X_L,+=3.95±0.09 \rmGeV and M_X_H,+=5.00±0.10 \rmGeV disfavor assigning the X(4140) to be the J^PC=1⁺⁺ diquark-antidiquark type cscs tetraquark state. Moreover, we obtain the masses of the J^PC=1^+- diquark-antidiquark type cscs tetraquark states as a byproduct. The present predictions can be confronted to the experimental data in the future.
