| 英文摘要 | A search for pair-production of supersymmetric particles under the assumption that R-parity is violated via a dominant LL (E) over bar coupling has been performed using the data collected by ALEPH at centre-of-mass energies of 130-172 GeV. The observed candidate events in the data are in agreement with the Standard Model expectation. This is translated into lower limits on the mass of charginos, neutralinos, sleptons, sneutrinos and squarks. For instance, charginos with masses less than 73 GeV/c(2) and neutralinos with masses less than 23 GeV/c(2) are excluded at 95% confidence level for any generation structure of the LL (E) over bar coupling, and for neutralino, slepton or sneutrino LSPs. |
