论文摘要
衰减$ d \toπ^+π^-e^+ν_e$和$ d_s \toπ^+π^-e^-e^+ν_e$用作检查量表中衰减到$π^+π^^ - $的构成$ q \ bar q $分量的探针。有很多具体的证据，以支持轻标量的异国情调的四夸克性质。同时，$ q^2 \ bar q^2 $模型有效性的进一步扩展在新工艺上似乎非常有趣和重要。我们分析了besiii和cleo的数据$ d^+\至π^+π^ - e^+ν_e$和$ d^+_ s \ toπ^+π^ - e^+ν_e$，并表明这些实验的结果可以解释为四分之一$ scalar messons $ $ $ $ f的四个Quark Antrom of Four sublark Menthy（500）$ f。我们的方法还可以应用于涉及光标量的其他类似衰变的描述。
Decays $D\toπ^+π^-e^+ν_e$ and $D_s\toπ^+ π^-e^+ν_e$ serve as probes that check the existence of constituent $q\bar q$ components in the wave functions of scalar mesons decaying into $π^+π^-$. 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 and CLEO data on the decays $D^+\to π^+π^- e^+ν_e$ and $D^+_s\to π^+π^- e^+ν_e$ and show that the results of these experiments together can be interpreted in favor of the four-quark nature of light scalar mesons $σ(500)$ and $f_0(980)$. Our approach can also be applied to the description of other similar decays involving light scalars.
