摘要
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 KSdetection with J / ψ MC samples and e^＋e^-→Hadrons MC samples.The results 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 study and cross section measurement for KS meson.
