  We study the prospects for detecting the sleptons of the Minimal
Supersymmetric Standard Model at hadron colliders and supercolliders. We use
ISAJET 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 $\sim 1$fb$^{-1}$ of integrated luminosity,
it will be very difficult to detect sleptons beyond the reach of LEP at the
Fermilab Tevatron $p\bar{p}$ collider, due to a large background from $W$ pair
production. At LHC, sleptons of mass up to 300 GeV ought to be detectable via
dilepton signal as long as it is possible to veto central jets with $p_T \geq
25$ GeV with high efficiency.
