Abstract
In this article, we construct the type tensor current to study the mass and width of the with the QCD sum rules in details. The predicted mass for the tetraquark state is in excellent agreement with the experimental data 4273.3 \pm 8.3 ^{+17.2}_{-3.6} \mbox MeV} from the LHCb collaboration. The central value of the width is in excellent agreement with the experimental data 56 \pm 11 ^{+8}_{-11} \mbox MeV}} from the LHCb collaboration. The present work supports assigning the to be the tetraquark state with a relative P-wave between the diquark and antidiquark constituents. Furthermore, we obtain the mass of the type tetraquark state with as a byproduct.
