In this article, we tentatively assign the to be the -type scalar tetraquark state and study its mass and width with the QCD sum rules; special attention is paid to calculating the hadronic coupling constants and concerning the tetraquark state. We obtain the values GeV and MeV, which are consistent with the experimental data. The numerical result supports assigning the to be the -type scalar tetraquark state.
