Abstract
Data taken with the High Resolution Spectrometer detector at the SLAC storage ring PEP were used to test QED to fourth order in the coupling constant 𝛼. The experiment studied four-lepton final states produced at high 𝑄2 in 𝑒+𝑒− interactions at √𝑠=29 GeV. All four final-state particles were detected at large angles with respect to the beam axis. We observed 17 𝑒+𝑒−𝑒+𝑒−, 24 𝑒+𝑒−𝜇+𝜇−, and 1 𝜇+𝜇−𝜇+𝜇− events with pair masses greater than 1 GeV/𝑐2 for an integrated luminosity of 291 pb−1. The complete 𝛼4 QED calculation agrees reasonably well with the data.
