| 中文摘要 | 强子事例的选择和强子探测效率是在BEPC/BES上进行R值测量的两项主要误差来源.过去实验只选取等于或者大于2叉的强子事例,因而0叉和1叉事例的丢失将导致强子事例数和强子探测效率的较大误差.试图提出在R值测量中选取包含1叉强子事例在内的样本,这将有助于更合理地调节强子事例产生器LUARLW的参数,减小强子探测效率和R值测量的系统误差.; Hadronic event selection and hadronic detection efficiency are two main sources of systematic error for the R measurement at BES/BEPC.If only the hadronic events with 2-prong and higher prong are selected as done in the previous measurements,the lost events with 0-prong and 1-prong will cause the systematic error for both of the number of hadronic events and the detection efficiency.This paper aims to present a new method to select the 1-prong hadronic events.It will be helpful to tune the parameters in hadronic events generator LUARLW more reasonably,and decrease the systematic errors of hadronic efficiency in R measurement.; 国家自然科学基金(10491300)资助~~ |
