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 (T0.8) 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. © 1988 The American Physical Society.
