The cross section and forward-backward muon charge asymmetry for the e+e-→μ+μ-γ reaction were measured to be σ=2.82±0.35 pb and A=-0.34±0.10 with the VENUS detector at TRISTAN at 〈√s〉=59.2GeV for an integrated luminosity of 53.5 pb-1. The measured cross section agrees with the theoretical prediction. The asymmetry result is consistent with the electroweak prediction but not with the QED prediction at the level of 2σ.
