Abstract

Physical review letters 44(26), 1722 - 1725 (1980). doi:10.1103/PhysRevLett.44.1722, This paper reports the results of a study of hadron production in e+e− collisions at c.m. system energies of 33, 35, and 35.8 GeV. Production of a new quark flavor has been sought. The measured values of the total cross section, the thrust distributions, and the study of inclusive muon production show no evidence for the production of a new charge-23e quark near threshold. In addition, during an energy scan in the region 29.9, Published by APS, College Park, Md.
