| 英文摘要 | We present a new calculation of the mass and width of the exotic 0(--) glueball in the framework of the QCD sum rules. We next construct a new current which couples to a pure 0(--) gluon state and derive consistent and stable sum rules. A previously used current in this approach was shown to be inconsistent. We obtain for this state a mass MG = 6.3(-1.1)(+0.8) GeV and an upper limit for the total width Gamma(G) <= 235 MeV. These values can be used as an important guide for the experimental search of this exotic state. We argue that the mixing of this glueball state with the 0(--) tetraquark is very small. Therefore, the exotic 0(--) glueball can be considered as a pure gluon state. |
