摘要	The results of searches for selectrons, charginos and neutralinos performed with the data collected by the ALEPH detector at LEP at centre-of-mass energies up to 209 GeV are interpreted in the framework of the Minimal Supersymmetric extension of the Standard Model with R-parity conservation. Under the assumptions of gaugino and sfermion mass unification and no sfermion mixing, an absolute lower limit of 73 GeV/c(2) is set on the mass of the lighter selectron (e) over tilde (R) at the 95% confidence level. Similarly, limits on the masses of the heavier selectron (e) over tilde (L) and of the sneutrino (nu) over tilde (e) are set at 107 and 84 GeV/c(2), espectively. Additional constraints are derived from the results of the searches for Higgs bosons. The results are also interpreted in the framework of minimal supergravity. (C) 2002 Elsevier Science B.V.
