Possible signals of constrained minimal supersymmetry at a high luminosity Fermilab Tevatron collider.

Abstract

We study the most promising signals of constrained minimal supersymmetry detectable at a luminosity upgraded 2 TeV Fermilab Tevatron collider. Using a full event-level Monte carlo program based on pythia and getset we simulate the trilepton signal examining in detail the effect of constraints on the parameter space. We also simulate the monolepton and dilepton signals, the E${\mathrm{/}}_{\mathit{T}}$+jets signal, and the signals of top squark production in supersymmetry all with full standard model backgrounds with realistic detector cuts. We find that large fractions of parameter space can be probed (or eliminated if no signal is found), but mass limits on charginos and neutralinos are not possible based solely on the trilepton signal. Detection efficiencies depend strongly on supersymmetry 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 CERN LEP II will complement searches at Fermilab. \textcopyright{} 1996 The American Physical Society.
