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 ϕ I . In this paper, we perform a detailed collider study for the signature of pp→G′→Θ→ggϕI→ggqq¯ $$ pp\to {G}^{\prime}\to \left(\varTheta\ \to gg\right)\left({\phi}_I\to ggq\overline{q}\right) $$ with the coloron G ′ as a six-jet resonance. For a light ϕ I 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 ϕ I case. Independent of whether ϕ I 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.
