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

Abstract

In this article, we tentatively assign the X∗(3860) to be the Cγ5 ⊗ γ5C type scalar tetraquark state, study its mass and width with the QCD sum rules, special attention is paid to calculating the hadronic coupling constants GXηcπ and GXDD concerning the tetraquark state. We obtain the values MX = 3.86±0.09GeV and ΓX = 202MeV with large uncertainty, which… (More)
