Physical Review D 31:9 (1985) 2352-2355
Abstract:
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 cosθ<0.55 gives a cross-section ratio of Rμμ=0.990±0.017±0.030. The resulting couplings of the weak neutral current are gaegaμ=0.208±0.064± 0.021 and gvegvμ=0.027 ±0.051±0.089. The QED cutoff parameters are Λ+>170 GeV and Λ->146 GeV at 95% C.L. © 1985 The American Physical Society.Study of quark fragmentation in e+e- annihilation at 29 GeV: Global jet parameters and single-particle distributions.
