Signals for the minimal gauge-mediated supersymmetry-breaking model at the Fermilab Tevatron collider

We investigate the experimental implications of the minimal gauge-mediated low energy supersymmetry-breaking model for Fermilab Tevatron collider experiments. We map out the regions of parameter space of this model that have already been excluded by collider searches and by limits on $b\to s\gamma$. We use ISAJET to compute the cross sections for a variety of topological signatures which include photons in assocation with multiple leptons, jets, and missing transverse energy. The reach in the parameter $\Lambda$, which fixes the scale of sparticle masses, is estimated to be $\sim 60$, 100, and 135 TeV for Tevatron integrated luminosities of 0.1, 2, and 25 fb${}^{-1}$, respectively. The largest signals occur in photon(s) plus lepton(s) plus multijet channels; jet-free channels containing just photons plus leptons occur at much smaller rates, at least within this minimal framework.
