| Description: |
We have tested QED to fourth order in the coupling constant α in the large-Q2 region by studying four-lepton final states in e+e- interactions with the Mark II detector at the SLAC storage ring PEP (s=29 GeV). All four final-state particles were detected at large angles with respect to the beam axis. For an integrated luminosity of 205 pb-1, we observed ten e+e-e+e-, ten e+e-μ+μ-, and one μ+μ-μ+μ- events with opposite-charge pair masses greater than 1 GeV/c2. These events show good agreement with the complete α4 QED calculation. |
