The characteristics of events originating from the production of new particles and the selection criteria used in the search for these particles are described. No candiates for new particles are found. Sequential heavy leptons are excluded to a mass of 22.4 GeV. The production of charged Higgs bosons with a mass between 4 and 16 GeV is excluded if the branching ratio of the charged Higgs boson to the tau is greater than 25 percent. The lower limit on the mass of scalar taus, the supersymmetric partners of the tau-lepton, is 17 GeV. Winos are excluded with a mass less than 23 GeV, a result which is very insensitive to the scalar neutrino mass, unless the scalar neutrino and the wino are almost degenerate in mass. Higgsinos are excluded to a mass of 22.3 GeV for both a right-handed and a left-handed coupling at the higgsino-photino-W-boson vertex. 收起
