Περίληψη:
Searches for charginos, neutralinos and sleptons at LEP2 centre-of-mass
energies from 130 GeV to 189 GeV have been used to set lower limits on
the mass of the Lightest Supersymmetric Particle and other
supersymmetric particles within the MSSM framework. R-parity
conservation has been assumed. The lightest neutralino was found to be
heavier than GeV/c(2) independent of the m(0) value. The Lightest
chargino, the second-to-lightest neutralino, the next-to-heaviest
neutralino, the heaviest neutralino, the sneutrino and the right-handed
selectron were found to be heavier than 62.4 GeV/c2, 62.4 GeV/c(2), 99.9
GeV/c(2), 116.0 GeV/c(2), 61.0 GeV/c(2), and 87.0 GeV/c(2),
respectively. These limits do not depend on m(0) or M-2 and are Valid
for 1 less than or equal to tan beta less than or equal to 40, in the mu
region where the lightest neutralino is the LSP. If the sneutrino is
heavier than the chargino the lightest neutralino has to be heavier than
32.4 GeV/c(2). The effects of mixings in the third family of sfermions
on these limits are discussed. The confidence level of all limits given
is 95%. (C) 2000 Published by Elsevier Science B.V.
