TL;DR: In this paper, a search has been made for the production of a new heavy lepton and for spin-0 supersymmetric partners of the muon and 95%-confidence-level lower limits of 16 GeV for the mass of the scalar partners were obtained.
Abstract: Data from the MARK-J detector on the reactions e/sup +/e/sup -/..--> mu../sup +/..mu../sup -/,tau/sup +/tau/sup -/ in the center-of-mass energy range from 12 to 36.7 GeV are presented. The ..mu..,tau radii are shown to be <10/sup -16/ cm. A search has been made for the production of a new heavy lepton and for the production of spin-0 supersymmetric partners of the muon. 95%-confidence-level lower limits of 16 GeV for the mass of a new charged heavy lepton and 15 GeV for the mass of the scalar partners of the muon are obtained.

TL;DR: In this article, the results of a study of hadron production in e/sup +/e/sup -/ collisions at c.m. energies of 33, 35, and 35.8 GeV were reported.
Abstract: This paper reports the results of a study of hadron production in e/sup +/e/sup -/ collisions at c.m. 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-2/3e quark near threshold. In addition, during an energy scan in the region 29.9< or =..sqrt..s< or =31.6 GeV, no hadron resonance indicating the existence of a bound state composed of charge-2/3e quarks has been found.
