| 英文摘要 | In order to solve the current experimental controversy on the existence of the tenser glueball xi(2230), we examine whether the conclusion from Seth's experimental measurement, which rejects existence of xi(2230), is reliable. We claim that the non-observation of the resonance structure by Seth is not a sound ground for rejecting the existence of xi(2230) but it may just indicate that xi(2230) has a broad width. We also study the tensor glueball properties: the mass, spin, and decay width. Our theoretical predictions of the mass and the spin of the xi(2230) using QCD sum rule are about 2.23 GeV and J = 2, respectively. Our theoretical results also evidently show that the xi(2230) must have a total decay width of about 100 MeV, which is much broader than the reported 20 MeV but a small partial decay width of 2 MeV into p (p) over bar decay channel. |
