Abstract

Searches for the production of supersymmetric particles under the assumption that R-parity is violated via a single dominant LLE¯,LQD¯ or U¯D¯D¯ coupling were performed. These use the data collected by the ALEPH detector at LEP at centre-of-mass energies from 188.6 to 201.6 GeV. The numbers of candidate events observed in the data are consistent with Standard Model expectations. Upper limits on the production cross sections and lower limits on the masses of charginos, sleptons, squarks and sneutrinos are derived.
