Search for pair-production of strongly-interacting particles decaying to pairs of jets in pp¯ collisions at s√=1.96 TeV


CDF Collaboration; et al; Canelli, F; Kilminster, B (2013). Search for pair-production of strongly-interacting particles decaying to pairs of jets in pp¯ collisions at s√=1.96 TeV. Physical Review Letters, 111(3):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.
