Search for Three-Jet Resonances in pp Collisions at sqrt(s) = 7 TeV

Understand

A model-independent search for three-jet hadronic resonance production in pp collisions at a center-of-mass energy of 7 TeV has been conducted by the CMS Collaboration at the LHC, using a data sample corresponding to an integrated luminosity of 35 inverse picobarns.

• Events with high jet multiplicity and a large scalar sum of jet transverse momenta are analyzed.
• The number of expected standard model background events is found to be in good agreement with the observed events.
• Limits are set on a model describing the production of R-parity-violating supersymmetric gluino pairs, and gluino masses in the range of 200 to 280 GeV/c^2 are excluded at a 95% confidence level for the first time.
