Search for R-parity violating decays of supersymmetric particles in $e^{+} e^{-}$ collisions at center-of-mass energies from 189-GeV to 202-GeV

Searches for the production of supersymmetric particles under the assumption that R-parity is violated via a single dominant LLE, LQD or UDD 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.
