通过分析BESIII探测器在质心能量为3.773 GeV处获得的积分光度数据，我们测量了Cabibbo有利强子衰变的分支分数，和，分别确定为，和，。支化分数的精度得到了显著提高，并首次观察到了支化过程和支化过程。
By analyzing andata sample corresponding to an integrated luminosity oftaken at a center-of-mass energy of 3.773 GeV with the BESIII detector, we measure the branching fractions of the Cabibbo-favored hadronic decays,, and, which are determined to be,, and, respectively. The precision of the branching fraction ofis significantly improved, and the processesandare observed for the first time.
