  Results are reported from a search for the production of three-jet resonances
in pp collisions at a center-of-mass energy sqrt(s) = 7 TeV. The study uses the
data sample collected by the CMS experiment at the LHC in 2011, corresponding
to an integrated luminosity of 5.0 inverse femtobarns. Events with high jet
multiplicity and a large scalar sum of jet transverse momenta are analyzed for
the presence of resonances in the three-jet invariant mass spectrum. No
evidence for a narrow resonance is found in the data, and limits are set on the
cross section for gluino pair prediction in an R-parity-violating supersymmetry
model, for gluino masses greater than 280 GeV. Assuming a branching fraction
for gluino decay into three jets of 100%, gluino masses below 460 GeV are
excluded at 95% confidence level. These results significantly extend the range
of previous limits.
