Search for Multijet Resonances in pp Collisions at sqrt s = 7 TeV

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 pb$^{-1}$. Events with high jet multiplicities and a large scalar sum of jet transverse momenta are analyzed. Good agreement is found between the expected Standard Model QCD background and all selected events, and limits are set on a model used to describe the production of RPV SUSY gluino pairs. These are the most stringent limits set to date on the production of three-jet hadronic resonances and the first limits from pp collisions.
