Description

The reaction e+e- → μ+μ- has been measured in the center-of-mass energy range 5.8--7.4 GeV. The polar-angle asymmetry agrees with second-order quantum electrodynamics. From this a 95% confidence limit of M/sub z/ > 53g/sub a//e GeV is placed on the mass to coupling constant ratio for a neutral vector boson
