  Single $s$-channel production of sleptons, such as $\tilde \tau$'s and/or
$\tilde \nu_\tau$, with their subsequent decay into purely leptonic or dijet
final states is possible in hadronic collisions via R-parity violating
couplings. We examine the impact of slepton production on bump searches in both
the Drell-Yan and dijet channels and examine whether the lepton charge
asymmetry in the $\ell\nu$ channel provides for additional search sensitivity.
As a consequence, search reaches in the slepton mass-R-parity violating
coupling plane are obtained for both the Tevatron and LHC. The possibility of
using the leptonic angular distributions and the lepton charge asymmetry to
distinguish slepton resonances from new gauge bosons is also analyzed.
