论文摘要
在BESIII数据中搜索张量粘合球,以辐射$ j/ψ$腐烂到$π^0π^0 $和$ k_sk_s $。 $ππ$不变的质量分布表现出一种增强功能,可以用$(2210 \ pm 60)-i(180 \ pm 60)$ \,$ \,MEV描述。我们推测张量粘合球是否可以分布在高质量张量中。
The tensor glueball is searched for in BESIII data on radiative $J/ψ$ decays into $π^0π^0$ and $K_sK_s$. The $ππ$ invariant mass distribution exhibits an enhancement that can be described by a pole at $(2210\pm 60) -i(180\pm 60)$\,MeV. We speculate if the tensor glueball could be distributed among high-mass tensor mesons.
