Detecting sleptons at hadron colliders and supercolliders

We study the prospects for detecting the sleptons of the minimal supersymmetric standard model at hadron colliders and supercolliders. We use i s a g e t 7.03 to simulate charged slepton and sneutrino pair production, incorporating slepton and sneutrino cascade decays into our analysis. We find that even with an accumulation of ∼1 ${\mathrm{fb}}^{\mathrm{-}1}$ of integrated luminosity, it will be very difficult to detect sleptons beyond the reach of CERN LEP at the Fermilab Tevatron pp¯ collider, due to a large background from W pair production. We confirm that at CERN LHC, sleptons of mass up to 300 GeV ought to be detectable via the dilepton signal as long as it is possible to veto central jets with ${\mathit{p}}_{\mathit{T}}$≥25 GeV with high efficiency.
