Analysis of the mass and width of the X*(3860) with QCD sum rules

Regular Article - Theoretical Physics

Abstract.

In this article, we tentatively assign the \(X^{\ast}(3860)\) to be the \(C\gamma_{5}\otimes \gamma_{5}C\)-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 \(G_{X\eta_{c}\pi}\) and \(G_{XDD}\) concerning the tetraquark state. We obtain the values \(M_{X}=3.86 \pm 0.09\) GeV and \( \Gamma_{X}= 202\pm 146\) MeV, which are consistent with the experimental data. The numerical result supports assigning the \(X^{\ast}(3860)\) to be the \( C\gamma_{5}\otimes \gamma_{5}C\)-type scalar tetraquark state.
