  Results are presented from searches for R-parity-violating supersymmetry in
events produced in pp collisions at sqrt(s) = 8 TeV at the LHC. Final states
with 0, 1, 2, or multiple leptons are considered independently. The analysis is
performed on data collected by the CMS experiment corresponding to an
integrated luminosity of 19.5 inverse femtobarns. No excesses of events above
the standard model expectations are observed, and 95% confidence level limits
are set on supersymmetric particle masses and production cross sections. The
results are interpreted in models featuring R-parity-violating decays of the
lightest supersymmetric particle, which in the studied scenarios can be either
the gluino, a bottom squark, or a neutralino. In a gluino pair production model
with baryon number violation, gluinos with a mass less than 0.98 and 1.03 TeV
are excluded, by analyses in a fully hadronic and one-lepton final state,
respectively. An analysis in a dilepton final state is used to exclude bottom
squarks with masses less than 307 GeV in a model considering bottom squark pair
production. Multilepton final states are considered in the context of either
strong or electroweak production of superpartners, and are used to set limits
on the masses of the lightest supersymmetric particles. These limits range from
300 to 900 GeV in models with leptonic and up to approximately 700 GeV in
models with semileptonic R-parity-violating couplings.
