Title: Hexapod coloron at the LHC

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 p p G ( Θ   g g ) ( ϕ I g g q q ¯ ) 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.
