M. Acciarri et al., Search for R-parity violating decays of supersymmetric particles e(+)e(-) collisions at root s=189 GeV, EUR PHY J C, 19(3), 2001, pp. 397-414
A search for chargino. neutralino and scalar lepton pair-production in e(di
vided by)-e(-) collisions at the centre-of-mass energy of 189 GeV is perfor
med under the assumptions that R-parity is riot conserved in decays and onl
y one of tile coupling constants lambda (ijk), lambda ' (ijk), gimel " (ijk
) is non-negligible. No signal is found in a data sample corresponding to a
rt integrated luminosity of 176.4pb(-1). Limits on the Minimal Supersymmetr
ic Standard model parameters and on the masses of supersymmetric particles
are derived.
