摘要：

本文考虑了手征对称性破缺效应、末态相互作用和重夸克对称性，研究了$ψ^{\prime}\to {J/ψ}π^+π^-$和$η_c^{\prime}\to {η_c}π^+π^-$衰变。我们可以将$η_c^{\prime}\to η_c π^+π^-$衰变宽度和微分衰变宽度的预言与实验数据进行对比，得到手征破缺效应和末态相互作用的有力约束，检验重夸克对称性。

英文摘要：

In this article, we study the decays $ψ^{\prime}\to {J/ψ}π^+π^-$ and $η_c^{\prime}\to {η_c}π^+π^-$ by taking into account the chiral symmetry breaking effects, the final-state interactions and the heavy quark symmetry. We can confront the predictions of the $η_c^{\prime}\to η_c π^+π^-$ decay width and differential decay width with the experimental data in the future, and obtain powerful constraints on the chiral breaking effects and the final-state interactions, and test the heavy quark symmetry.
