published as Phys.Rev.D53:5253-5257,1996 · 12 pages, LaTeX, 4 figures (included) Slightly revised version to appear in Phys. Rev. D (May 1 issue); noted that trilepton searches cannot probe the full parameter space of the model because the leptons from neutralino decay become too soft to be detectable

We reexamine the phenomenological aspects of a recently proposed string-derived SU(5)\ifmmode×\else\texttimes\fiU(1) one-parameter supergravity model, and explore the sensitivity of the model predictions to variations in the strong coupling and the string unification scale. We also perform an analysis of the constraints on the parameter space of the model in light of the recent Fermilab Tevatron trilepton data and the CERN LEP 1.5 chargino and slepton data. We obtain m_\mathrm\ensuremathχ1^\ifmmode±\else\textpm\fi\ensuremath\gtrsim70 GeV, which excludes one-third of the parameter space of the model. The remainder of the parameter space should be probed by ongoing analyses of the Tevatron trilepton data and forthcoming LEP 2 runs. \textcopyright 1996 The American Physical Society.
