摘要：

我们用QCD求和规则研究了$C=+$中的二胶子胶球和三胶子胶球。我们系统地构造了它们的内插电流，发现$C=+$的自旋1电流全部消失.这表明$C=+$的“基态”自旋1胶球在相对论框架内不存在。计算了含$J^{PC} = 0^{\pm+}/2^{\pm+}$的两胶子胶球和含$J^{PC} = 0^{\pm+}/2^{\pm+}$的三胶子胶球的质量。我们建议在未来的BESIII、GESIX、LHC和PANDA实验中寻找$J^{PC} = 0^{-+}/2^{-\pm}/3^{\pm-}$三胶子胶子球的三介子衰变通道。

英文摘要：

We study two- and three-gluon glueballs of $C=+$ using the method of QCD sum rules. We systematically construct their interpolating currents, and find that all the spin-1 currents of $C=+$ vanish. This suggests that the ``ground-state'' spin-1 glueballs of $C=+$ do not exist within the relativistic framework. We calculate masses of the two-gluon glueballs with $J^{PC} = 0^{\pm+}/2^{\pm+}$ and the three-gluon glueballs with $J^{PC} = 0^{\pm+}/2^{\pm+}$. We propose to search for the $J^{PC} = 0^{-+}/2^{-\pm}/3^{\pm-}$ three-gluon glueballs in their three-meson decay channels in future BESIII, GlueX, LHC, and PANDA experiments.
