Colored Resonances at the Tevatron: Phenomenology and Discovery Potential in Multijets

TL;DR

This paper introduces a coloron—a massive spin-1 color-octet bound state—that can dominantly decay to hyper-pions, producing a characteristic multi-jet resonance. By constructing a renormalizable HC-inspired model and a corresponding phenomenological Lagrangian, the authors map HC parameters to QCD analogs, show consistency with existing bounds, and propose a Tevatron-focused four-jet search strategy that exploits secondary resonances. They demonstrate strong discovery potential for colorons at m_{tilde{rho}} roughly 350–600 GeV, with significant signal over QCD background in both model-dependent and inclusive analyses. The work highlights a compelling Tevatron niche for color-octet states and discusses how collider reach shifts with coupling structures and LHC conditions.

Abstract

There exist several classes of theories beyond the Standard Model which contain massive spin-1 color octets, generically called "colorons". Indeed we argue that colorons inevitably appear in the spectrum whenever new colored particles feel an additional confining force. Colorons are distinctive at hadron colliders as this is the only environment in which they can be resonantly produced. In the simplest models we show that the coloron naturally decays to multijets via secondary resonances, which can be consistent with all existing bounds, even for colorons as light as a few hundred GeV. We perform representative case studies and show that a search in the four-jet channel at the Tevatron has strong signal significance, while the LHC faces formidable challenges for such a search.
