摘要
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-->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 similar to 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.
