Search for scalar leptons in e+e- collisions at centre-of-mass energies up to 209GeV
ALEPH Collaboration
TL;DR
This paper reports a search for scalar leptons (selectron, smuon, stau) in electron-positron collisions at energies up to 209 GeV, finding no evidence of new particles and setting mass limits.
Contribution
It provides the first comprehensive search for scalar leptons at LEP energies and establishes new mass exclusion limits.
Findings
Candidate events are consistent with Standard Model background.
No evidence for scalar lepton production was observed.
New mass limits for selectron, smuon, and stau are reported.
Abstract
A search for selectron, smuon and stau pair production is performed with the data collected by the ALEPH detector at LEP at centre-of-mass energies up to 209 GeV. The numbers of candidate events are consistent with the background predicted by the Standard Model. Final mass limits from ALEPH are reported.
