Abstract

By studying e+e- annihilations in the center-of-mass energy range between 50 and 60.8 GeV, we have established a 95%-confidence-level lower limit on the mass of a fourth-generation charge -(1/3 quark b of 27.2 GeV. In contrast with all previous searches, this limit has been obtained through consideration of the decay processes b'b and b'bg aswell as b'cW-. For the cases where any one of the three decay modes dominates, we obtain higher mass limits.
