Search for R-Parity Violating Decays of Supersymmetric Particles in e+e- Collisions at Centre-of-Mass Energies between 189-208 GeV

Searches for the pair-production of supersymmetric particles under the assumption that R-parity is violated via a single dominant LLE, LQD or UDD coupling are performed using the data collected by the ALEPH detector at LEP with centre-of-mass energies from 188.6 GeV to 208.1 GeV. The observed candidate events in the data are in agreement with the Standard Model expectation, and limits on the production cross-sections and the masses of charginos, sleptons, squarks and sneutrinos are derived.
