Abstract

We searched for possible signatures of top-quark production in 508 $e^{+} e^{-}$ hadronic annihilation events collected at $\sqrt{s} = 52$ GeV by the TOPAZ detector at the KEK $e^{+} e^{-}$ collider TRISTAN. The observed hadronic cross section and shape of hadronic events are consistent with the standard-model predictions without top quarks. A lower limit (95% confidence level) on the mass of the lightest top meson is set at 25.8 GeV.
