Abstract
Instead of the usual dijet decay, the coloron may mainly decay into its own “Higgs bosons”, which subsequently decay into many jets. This is a general feature of the renormalizable coloron model, where the corresponding “Higgs bosons” are a color-octet Θ and a color-singlet ϕI. In this paper, we perform a detailed collider study for the signature of \( pp\to {G}^{\prime}\to \left(\varTheta\ \to gg\right)\left({\phi}_I\to ggq\overline{q}\right) \) with the coloron G′ as a six-jet resonance. For a light ϕI below around 0.5 TeV, it may be boosted and behave as a four-prong fat jet. We also develop a jet-substructure-based search strategy to cover this boosted ϕI case. Independent of whether ϕI is boosted or not, the 13 TeV LHC with 100 fb−1 has great discovery potential for a coloron with the mass sensitivity up to 5 TeV.
