论文摘要
基于BESIII的测量值,对$ d_s^+\至π^+π^0π^0 $的反应,我们通过考虑单一手性方法中的$ s $ - 波 - 波 - 波及以下的互动来调查此过程,以及中间的共鸣$ f_0 $ f_0(13700)$ f_2(1370)$ f_2(1370)(1370)(1370)。我们的计算可以合理地重现实验数据,我们的结果意味着,$ f_0(980)$是由$ s $ - 波及伪符号符合符号的互动而动态产生的,在此过程中起着重要作用,在此过程中起着重要的作用,以及来自InterMendiapeRiage的贡献,以及中间的共鸣$ f_0(1370)$ f_0(1370)$和$ f_2($ f_2(1270)(1270)(1270)(1270)。将来对此过程的更精确的测量可能会阐明$ f_0(1370)$和$ f_2(1270)$的性质。
Based on the BESIII measurements on the reaction of $D_s^+\to π^+π^0π^0$, we investigate this process by considering the $S$-wave pseudoscalar-pseudoscalar interaction within the unitary chiral approach, and the contributions from the intermediate resonances $f_0(1370)$ and $f_2(1270)$. Our calculation could reasonably reproduce the experimental data, and our results imply that the $f_0(980)$, dynamically generated from the $S$-wave pseudoscalar-pseudoscalar interaction, plays an important role in this process, and the contributions from the intermediate resonances $f_0(1370)$ and $f_2(1270)$ are also necessary. The more precise measurements of this process in future could shed light on the nature of the $f_0(1370)$ and $f_2(1270)$.
