  Right-handed neutrinos offer us the possibility of accommodating neutrino
masses. In a supersymmetric model, this implies the existence of right-handed
sneutrinos. Right-handed sneutrinos are expected to be as light as other
supersymmetric particles if the neutrinos are Dirac fermions, or if the
lepton-number breaking scale is at (or below) the supersymmetry (SUSY) breaking
scale, assumed to be around the electroweak scale. Depending on the mechanism
of SUSY breaking, the lightest right-handed sneutrino may be the lightest
supersymmetric particle (LSP). We consider the unique hadron collider
signatures of a weak scale right-handed sneutrino LSP, assuming R-parity
conservation. For concreteness, we concentrate on stop pair-production and
decay at the Tevatron and the Large Hadron Collider, and briefly comment on the
production and decay of other supersymmetric particles.
