Query: Search for SUSY with R-parity violating LL\bar{E} couplings at sqrt(s) =
  189 GeV   Searches for pair production of supersymmetric particles under the assumption
that R-parity is not conserved are presented, based on data recorded by the
DELPHI detector in 1998 from e+e- collisions at a centre-of-mass energy of 189
GeV. Only one R-parity violating LL\bar{E} term (i.e. one lambda coupling),
which couples scalar leptons to leptons, is considered to be dominant at a
time. Moreover, it is assumed that the strength of the R-parity violating
couplings is such that the lifetimes can be neglected. The search for pair
production of neutralinos, charginos and sleptons has been performed for both
direct R-parity violating decays and indirect cascade decays. The results are
in agreement with Standard Model expectations, and are used to update the
constraints on the MSSM parameter values and the mass limits previously derived
at sqrt(s) = 183 GeV. The present 95% C.L. limits on supersymmetric particle
masses are: m_{\tilde{\chi}^0} > 30 GeV/c^2 and m_{\tilde{\chi}^\pm} > 94
GeV/c^2; m_{\tilde{\nu}} > 76.5 GeV/c^2 (direct and indirect decays);
m_{\tilde{\ell}_R} > 83 GeV/c^2 (indirect decay only).
