In particle physics, a slepton is a hypothetical bosonic partner of a lepton whose existence is implied by supersymmetry. Examples include: the selectron, the smuon, the stauon and the sneutrinos.

Search for supersymmetric particles in light gravitino scenarios and sleptons NLSP (182 words)
A search for sleptons, neutralinos, charginos, sgoldstinos and heavy stable charged sleptons in the context of scenarios where the lightest su per sym me tric particle is the gravitino, is presented.
Data collected during 2000 with the DELPHI detector at centre-of-mass energies from 204 to 208 GeV were analysed and combined with all the data collected from 1995 to 1999 at lower energies.
No evidence for the production of sleptons, neutralinos and charginos has been found, therefore new limits on the mass of these supersymmetric particles and on the model parameter space are set.
ALEPH Supersymmetry Studies at Sheffield (1114 words)
Another possible decay of the slepton, in the gauge-mediated supersymmetry breaking framework, is into a normal lepton and an invisible gravitino.
We are searching for short-lived sleptons, which are observed due to the fact that their decay products do not appear to originate at the primary vertex, and for sleptons with an intermediate lifetime, where the tracks show a distinct kink within the detector.
If interpreted as a genuine slepton decay, this could be a selectron decaying into an electron and an unseen gravitino, generating the visible kink.
