Abstract
A search for three-jet hadronic resonance production in 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 . Events with high jet multiplicity and a large scalar sum of jet transverse momenta are analyzed using a signature-based approach. The number of expected standard model background events is found to be in good agreement with the observed events. Limits on the cross section times branching ratio are set in a model of gluino pair production with an -parity-violating decay to three quarks, and the data rule out such particles within the mass range of 200 to .

Controlling for the “look-elsewhere effect”
Published 29 August 2011
When searching for new physics at the Large Hadron Collider, researchers have to keep track of how many places they look.
