论文摘要
我们通过计算其两体和三体衰减到向量和轴 - 矢量夸克 - 易夸克·梅森领域来恢复对地面伪尺度粘合球的调查，$ j^{pc} = 0^{ - +} $。我们通过将伪粘合球的质量设置为lattice QCD模拟预测的，通过将伪粘合球的质量设置为$ 2.6 $ GEV来评估分支比率。我们在besiii实验中复制了伪粘液粘合球质量的分支比率的计算，该计算与$ 2.37 $ GEV相匹配，该计算与测量的共振$ x（2370）$相匹配。目前的渠道和状态可能会达到目前的渠道，并且对于运行的BESIII和BELLE-II实验以及Fair/GSI的计划中的熊猫实验很有趣，这将能够在可访问的能量范围内检测到伪斯卡利亚粘合球。
We resume the investigation of the ground-state pseudoscalar glueball, $J^{PC}=0^{-+}$, by computing its two- and three-body decays into vector and axial-vector quark-antiquark meson fields additional to scalar and pseudoscalar mesons through the construction of an interaction chiral Lagrangian that produces these decays. We evaluate the branching ratio, via a parameter-free calculation, by setting the mass of the pseudoscalar glueball to $2.6$ GeV as predicted by lattice QCD simulations. We duplicate the computation for the branching ratios for a pseudoscalar glueball mass $2.37$ GeV which matches to the measured mass of the resonance $X(2370)$ in the BESIII experiment. The present channels and states are potentially reached and are interesting for the running BESIII and Belle-II experiments and the planned PANDA experiment at FAIR/GSI which will be able to detect the pseudoscalar glueball within the accessible energy range.
