Abstract

The three reactionse +ee +ee+e,e + e -e + e -μ+μ- ande + e -→μ+μ-μ+ μ- have been studied using the CELLO detector at PETRA. The data correspond to 130 pb−1 collected at energies ranging from 35 GeV to 46.8 GeV. A detailed analysis of the distribution of the observed events in phase space shows good agreement with QED to order α4.
