Lepton charge asymmetry enhances search sensitivity.

Angular distributions help distinguish sleptons from gauge bosons.

Abstract

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.
