Abstract

A search for new stable charged particles produced in pairs in the decays of the intermediate vector boson Z is performed with the MARK II detector at the SLAC Linear Collider. Particle masses are determined from momentum, ionization energy loss and time-of-flight measurements. No candidates for new particles are found. A limit excluding the production of pairs of stable fourth generation charged leptons and stable mirror fermions with masses between the muon mass and 36.3 GeV/c^2 is set at the 95% confidence level. The production of pairs of stable supersymmetric scalar leptons with masses between the muon mass and 32.6 GeV/c^2 is also excluded at the 95% confidence level under the assumption that the left- and right-handed scalar leptons are degenerate in mass.
