| 英文摘要 | 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. |
