| 英文摘要 | Motivated by the recent bes observation of the pp enhancement near threshold in radiative j/psi decays, x(1860) and x(1835), we choose the 0(-+) trigluonium state as a possible candidate and calculate its mass with qcd sum rules, which is found to be approximately in the region between 1.9gev and 2.7gev with some theoretical uncertainties. with the fact that the new bes resonance exhibits the behavior of this trigluon state, our analyses favor the baryonium-gluonium. mixing picture for the bes observation. |
