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

In this article, we tentatively assign the X*(3860) to be the C gamma(5) circle times gamma C-5-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 GX eta(c)pi and G(XDD) concerning the tetraquark state. We obtain the values M-X = 3.86 +/- 0.09 GeV and Gamma(X) = 202 +/- 146MeV, which are consistent with the experimental data. The numerical result supports assigning the X*(3860) to be the C gamma(5) circle times gamma C-5-type scalar tetraquark state.
