In this article, we construct both the ![$$[sc]_T[{\bar{s}}{\bar{c}}]_A+[sc]_A[{\bar{s}}{\bar{c}}]_T$$](/articles/epjc/abs/2019/01/10052_2019_Article_6596/10052_2019_Article_6596_tex_eq1.png)
type and ![$$[sc]_T[{\bar{s}}{\bar{c}}]_V-[sc]_V[{\bar{s}}{\bar{c}}]_T$$](/articles/epjc/abs/2019/01/10052_2019_Article_6596/10052_2019_Article_6596_tex_eq2.png)
type axialvector currents with 
to study the mass of the X(4140) with the QCD sum rules. The predicted masses support assigning the X(4140) to be the type axialvector tetraquark state. Then we study the hadronic coupling constant 
with the QCD sum rules based on solid quark-hadron duality, and obtain the decay width 
, which is in excellent agreement with the experimental data 
from the LHCb collaboration.
