Searches for the pair production of supersymmetric particles under the assumption that R-parity is violated via a single dominant , or coupling are performed using the data collected by the ALEPH detector at LEP at centre-of-mass energies from 189 to 209GeV . The numbers of observed candidate events in the data are in agreement with the Standard Model expectation, and limits on the production cross sections and on the masses of charginos, sleptons, squarks and sneutrinos are derived.
