摘要：

The process e+e- --> e+e-mu+-mu- has been studied in single-tag and double-tag configurations using the TOPAZ detector at TRIS-TAN. The data correspond to the integrated luminosity of 45.3 pb-1 at center-of-mass energies ranging from 52 to 61.4 GeV. The observed events in both configurations have shown a good agreement with QED predictions in order alpha-4. Although the AMY group reported an excess of e+e- --> e+e-mu+-mu- events in double-tag mode at low muon invariant mass region less than 1.0 GeV/c2, we did not observe such excess in our data.
