Abstract
A search for stable and long-lived massive particles of electric charg e \Q/e\ = 1 or 2/3, pair-produced in e(+)e(-) collisions at centre-of- mass energies from 130 to 183 GeV, is reported by the OPAL collaborati on at LEP. No evidence for production of these particles was observed in a mass range between 45 and 89.5 GeV. Model-independent upper limit s on the production cross-section between 0.05 and 0.19 pb have been d erived for scalar and spin-1/2 particles with charge +/- 1. Within the framework of the minimal supersymmetric model (MSSM), this implies a lower limit of 82.5 (83.5) GeV on the mass of long-lived right- (left- )handed scalar muons and scalar taus. Long-lived charged leptons and c harginos are excluded for masses below 89.5 GeV. For particles with ch arge +/- 2/3 the upper limits on the production cross-section vary bet ween 0.05 and 0.2 pb. All limits, on masses and on cross-sections, are valid at the 95% confidence level for particles with lifetimes longer than 10(-6) s. (C) 1998 Elsevier Science B.V. All rights reserved.
