Subtraction of beam-associated background in R measurement
Le résumé fourni par la source
Using R scan data collected at BES II detector, we study the character of beam-associated background. We use the method of f factor and the fitting of event vertices to subtract the residual beam-associated background. The difference between the R values obtained by using these two methods is between 0.3% and 2.3%
