Abstract
We study the most promising signals of constrained minimal supersymmet ry detectable at a luminosity upgraded 2 TeV Fermilab Tevatron collide r. Using a full event-level Monte Carlo program based on PYTHIA and JE TSET we simulate the trilepton signal examining in detail the effect o f constraints on the parameter space. We also simulate the monolepton and dilepton signals, the E(T)+jets signal, and the signals of top squ ark production in supersymmetry all with full standard model backgroun ds with realistic detector cuts. We find that large fractions of param eter space can be probed (or eliminated if no signal is found), but ma ss limits on charginos and neutralinos are not possible based solely o n the trilepton signal. Detection efficiencies depend strongly on supe rsymmetry parameters beyond simply the neutralino and chargino masses; analyses (experimental or theoretical) that do not include this will draw misleading conclusions. Finally, we comment on how searches at CE RN LEP II will complement searches at Fermilab.
