Resumen
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 ẽ R at the 95% confidence level. Similarly, limits on the masses of the heavier selectron ẽ L and of the sneutrino ṽ e are set at 107 and 84 GeV/c 2, respectively. Additional constraints are derived from the results of the searches for Higgs bosons. The results are also interpreted in the framework of minimal supergravity.
