A Study of the Processes of e+e→e+e+μ at Large Angle and Measured Luminosities

  • Using the BES data collected at √S=4.03GeV.the QED processes of e+e→e+e+μ have been studied. Our measurements agree with the QED prediction,and luminosities obtained from these two final states are compatible at a level of 4%.The total integrated luminosity of 23.1pb-1 was given for all data collected at this energy region from the calculation.

Abstract: Using the BES data collected at √S=4.03GeV.the QED processes of e+e→e+e+μ have been studied. Our measurements agree with the QED prediction,and luminosities obtained from these two final states are compatible at a level of 4%.The total integrated luminosity of 23.1pb-1 was given for all data collected at this energy region from the calculation.
