基于北京谱仪Ⅲ的离线软件系统,利用J/ψ蒙特卡罗样本和e~+e~-→强子的蒙特卡罗样本对单举K_S介子的探测效率展开了研究.结果表明两种样本K_S介子的某些主要动力学分布有一定差异,这些差异最终导致单举K_S介子总体探测效率约相差3%.该研究为后续对K_S介子的背景研究及截面谱测量提供了重要的参考价值.

Based on BESIII Offline Software System,we performed a study on the efficiency for inclusive KS detection with J/ψ MC samples and e+e-→Hadrons MC samples. The re￣sults show that there are differences in some main dynamic distributions of two samples, which leads to about 3% difference of the overall efficiency for inclusive KS detection.This study provides important information for the background stud...
