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

TL;DR

This paper explores the phenomenology of color-octet vector resonances called colorons, highlighting their potential to be discovered in multijet final states at hadron colliders like the Tevatron and LHC.

Contribution

It demonstrates that colorons naturally arise in theories with new colored particles and confining forces, and analyzes their decay signatures and discovery prospects at colliders.

Findings

Colorons can decay into multijets via secondary resonances.

Tevatron searches in four-jet channels have high discovery potential.

LHC faces challenges in detecting colorons in similar channels.

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.
