论文摘要
Inspired by recent BESIII's amplitude analysis on $D_s^+\toπ^+π^0π^0$, we develop a model based on the chiral unitary approach to discribe the $D_s^+\toπ^+π^0π^0$ decay, where $D_s^+$ decays into a $π^+$ and a quark-antiquark pair through weak decay of charm quark. Quark-Antiquark对强调产生的伪内膜的相互作用将导致动态生成$ F_0（980）$。我们的型号中还包括来自Besiii Fit中$ f_0（1370）$和$ f_2（1270）$的主要振幅。我们的型号也包括在内。除上述贡献外，要获得良好的合身性，我们还向我们的型号添加了共鸣$ f_2（1430）$的幅度。我们的型号适合$ m_ {π^0π^0} $和$ m_ {π^+π^0} $同时不变质量分布。
Inspired by recent BESIII's amplitude analysis on $D_s^+\toπ^+π^0π^0$, we develop a model based on the chiral unitary approach to discribe the $D_s^+\toπ^+π^0π^0$ decay, where $D_s^+$ decays into a $π^+$ and a quark-antiquark pair through weak decay of charm quark. The interaction of pseudoscalar mesons produced by the hadronization of quark-antiquark pair will lead to dynamically generated $f_0(980)$. The dominant amplitudes from resonances $f_0(1370)$ and $f_2(1270)$ in BESIII fit are also included in our model. In addition to above contributions, to obtain a good fit we also add a amplitude from resonance $f_2(1430)$ to our model. Our model fits well $M_{π^0π^0}$ and $M_{π^+π^0}$ invariant mass distributions simultaneously.
