  Results are reported from a search for R-parity violating supersymmetry in
proton-proton collision events collected by the CMS experiment at a
center-of-mass energy of sqrt(s) = 8 TeV. The data sample corresponds to an
integrated luminosity of 17.6 inverse femtobarns. This search assumes a minimal
flavor violating model in which the lightest supersymmetric particle is a
long-lived neutralino or gluino, leading to a signal with jets emanating from
displaced vertices. In a sample of events with two displaced vertices, no
excess yield above the expectation from standard model processes is observed,
and limits are placed on the pair production cross section as a function of
mass and lifetime of the neutralino or gluino. At 95% confidence level, the
analysis excludes cross sections above approximately 1 fb for neutralinos or
gluinos with mass between 400 and 1500 GeV and mean proper decay length between
1 and 30 mm. Gluino masses are excluded below 1 and 1.3 TeV for mean proper
decay lengths of 300 micrometers and 1 mm, respectively, and below 1.4 TeV for
the range 2-30 mm. The results are also applicable to other models in which
long-lived particles decay into multijet final states.
