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 (l) over tilde --> l chi, (t) over tilde --> bl<(nu)over tilde>, (b) over tilde --> b chi, and (q) over tilde --> q chi. Improved mass lower limits have been obtained in the framework of the Minimal Supersymmetric Standard Model..
