Popis: We have measured the process e+e-→μ+μ- at s =29 GeV using the High Resolution Spectrometer at SLAC PEP. The forward-backward charge asymmetry is Aμμ=-(4.9±1.5±0.5)% based on 5057 events. A subsample of 3488 μ+μ- events in the angular range cosθ170 GeV and Λ->146 GeV at 95% C.L. © 1985 The American Physical Society.
