Abstract

Multihadronic

e^{+} e^{-}

annihilation events containing final-state leptons have been investigated with a 4.7-

{pb}^{- 1}

data sample at c.m. energies of 50 and 52 GeV. The number of low-thrust events (

T \leq 0.8

) with isolated leptons is consistent with the expectation of the standard model with five quark flavors. Limits on the production of new quarks and leptons are reported.
