Abstract

The data collected at a centre-of-mass energy of 188.6 GeV by ALEPH at LEP, corresponding to an integrated luminosity of 173.6 pb-1, are analysed in a search for the scalar partners of quarks and leptons predicted in supersymmetric models. No evidence for any such particles was found in the decay channels ℓ̃→ℓX, t̃→cX, t̃→bℓṽ, b̃→bX, and q̃ → q X. Improved mass lower limits have been obtained in the framework of the Minimal Supersymmetric Standard Model. © 1999 Published by Elsevier Science B.V. All rights reserved.
