论文摘要
有很多具体的证据，以支持轻标量的异国情调的四夸克性质。同时，$ q^2 \ bar q^2 $模型有效性的进一步扩展在新工艺上似乎非常有趣和重要。我们分析了有关衰减$ j/ψ\至γπ^0π^0 $的BESIII数据，并表明该高统计实验的结果可以解释以偏向于光标量介子$ f_0（980）$和$ f_0（500）$的四夸克性质。
There exists a great deal of concrete evidence in favor of the exotic four-quark nature of light scalars. At the same time, the further expansion of the area of the $q^2\bar q^2$ model validity for light scalars on ever new processes seems extremely interesting and important. We analyze the BESIII data on the decay $J/ψ\to γπ^0π^0$ and show that the results of this high-statistics experiment can be interpreted in favor of the four-quark nature of light scalar mesons $f_0(980)$ and $f_0(500)$.
