Abstract
A search for pair-production of supersymmetric particles under the
assumption that R-parity is violated via a dominant 
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/c2 and neutralinos
with masses less than 23 GeV/c2 are excluded at 95% confidence level for
any generation structure of the coupling, and for
neutralino, slepton or sneutrino LSPs.
