Abstract (data abstract)
KEK-TRISTAN. Study of e+ e- --& gt; mu+ mu-, e+ e- --& gt; tau+ tau- and e+ e- --& gt; hadrons. This paper presents new results on R and the asymmetry for sqrt(s) 61.4 to 64.0 and combines with previously published VENUS data to give an experimental limit of 426 GeV (90 pct cl.) for the mass of an extra-Z boson produced in the annihilation interaction.
