利用BESIII探测器在质量中心能量为4.178 ~ 4.226 GeV处收集的总积分光度对应的湮灭数据，我们首次对衰变进行了幅度分析。在附近的质谱中观察到一个增强，这在早期的工作中没有看到，这意味着存在同位旋1的伙伴。衰变的分支分数为B(Ds+→KS0KS0π+)=(0.68±0.04stat±0.01syst)%。
Usingannihilation data corresponding to a total integrated luminosity ofcollected at center-of-mass energies between 4.178 and 4.226 GeV with the BESIII detector, we perform an amplitude analysis of the decayfor the first time. An enhancement is observed in themass spectrum near, which was not seen inin an earlier work, implying the existence of an isospin one partner of the. The branching fraction of the decayis determined to be B(Ds+→KS0KS0π+)=(0.68±0.04stat±0.01syst)%.
