Search for light- and heavy-flavor three-jet resonances in multijet final states at 8 TeV

A search for three-jet hadronic resonance production in pp collisions at a center-of-mass energy of 8 TeV has been conducted by the CMS Collaboration at the LHC with a data sample corresponding to an integrated luminosity of 19.5 fb$^{-1}$. The search method is model independent for events with high jet multiplicity and a large value of the scalar sum of jet transverse momenta; however, event selection is optimized using $R$-parity-violating supersymmetric models with gluino pair production in a six-jet final state. Gluino models explored include final states with either only light-flavor jets or those that include heavy-flavor quarks. Good agreement is found between the selected events and the expected standard model multijet and t$\bar{\textrm{t}}$ backgrounds, and the most stringent limits to date are set on the production of heavy-flavor $R$-parity-violating supersymmetric gluinos.
