Supersymmetry at a proposed sqrt s =4 TeV upgrade of the Fermilab Tevatron.
Additional Document Info
We study the signals for supersymmetry at the Fermilab Tevatron and its proposed energy upgrade (called the DiTevatron here) (s =4 TeV) in various well-motivated supersymmetric models. We consider the trilepton signature in the decay of pair-produced charginos and neutralinos, the missing energy signature in gluino and squark production, and the bb signal in the decay of the lightest supersymmetric Higgs boson produced in association with a W or Z boson. In each case we perform signal and background studies, using Monte Carlo and/or real data to estimate the sensitivity to these signals at the Tevatron and DiTevatron with the Main Injector, for short- and long-term integrated luminosities of scrL=10 and 25 fb-1, and 5 statistical significance. We conclude that one could probe chargino masses as high as m1180 (200) GeV, gluino masses as high as mg450 (750) GeV, and lightest Higgs boson masses as high as mh110 (120) GeV at the Tevatron (DiTevatron). A high-luminosity option at the Tevatron (1033 cm-2 s-1) may compensate somewhat for the higher reach of the DiTevatron, but only in the trilepton and Higgs signals. However, these gains may be severely compromised once the multiple-interaction environment of the high-luminosity Tevatron is accounted for. 1994 The American Physical Society.
