Title

Search for Pair Production of Strongly Interacting Particles Decaying to Pairs of Jets in pp Collisions at √s=1.96  TeV

CollaborationWith : Clark, Allan Geoffrey / Wu, Xin
Published in Physical Review Letters. 2013, vol. 111, no. 03, p. 031802
Abstract We present a search for the pair production of a narrow nonstandard-model strongly interacting particle that decays to a pair of quarks or gluons, leading to a final state with four hadronic jets. We consider both nonresonant production via an intermediate gluon as well as resonant production via a distinct nonstandard-model intermediate strongly interacting particle. We use data collected by the CDF experiment in proton-antiproton collisions at s√=1.96  TeV corresponding to an integrated luminosity of 6.6  fb−1. We find the data to be consistent with nonresonant production. We report limits on σ(pp→jjjj) as a function of the masses of the hypothetical intermediate particles. Upper limits on the production cross sections for nonstandard-model particles in several resonant and nonresonant processes are also derived.
