Weak Neutral-Current Effects in e/sup +/e/sup -/. -->. mu. /sup +/. mu. /sup -/ at 29 GeV
Description
We present a measurement of the cross section for production of collinear muon pairs based upon a sample of more than 10,000 events observed in the MAC detector at PEP. From the asymmetry A/sub ..mu mu.. = -0.058 +- 0.010 we find the axial vector weak neutral coupling to be given by g/sub A//sup e/g/sub A//sup ..mu../ = 0.24 +- 0.04.
