摘要:

有大量的具体证据支持光标量的奇异四夸克性质。与此同时,进一步扩展$q^2\bar q^2$模型在新过程中对轻标量的有效性似乎是非常有趣和重要的。我们分析了BESIII实验中关于$J/ψ\to γπ^0π^0$衰变的数据,结果表明这个高统计实验的结果可以解释为轻标量介子$f_0(980)$和$f_0(500)$的四夸克性质.

英文摘要:

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 $f_0(500)$.
