Searching for Colorons at the Large Hadron Collider

TL;DR

This paper explores the potential to discover massive color-octet vector bosons, called colorons, at the LHC by analyzing their decay into multiple gluons and estimating the mass ranges where discovery is feasible.

Contribution

It presents a phenomenological analysis of coloron production and decay at the LHC, including background estimation and discovery potential for various masses and luminosities.

Findings

A 5σ discovery is possible for colorons with mass up to 1650 GeV.

Coloron decay into eight gluons can be detected with specific cuts and luminosities.

The study provides mass reach estimates for different experimental scenarios.

Abstract

We investigate the prospects for the discovery of massive color-octet vector bosons at the CERN Large Hadron Collider with $\sqrt{s} = 14$ TeV. A phenomenological Lagrangian is adopted to evaluate the cross section of a pair of colored vector bosons (colorons, $\tilde{\rho}$) decaying into four colored scalar resonances (hyper-pions, $\tilde{\pi}$), which then decay into eight gluons. We include the dominant physics background from the production of $8g,7g1q, 6g2q$, and $5g3q$, and determine the masses of $\tilde{\pi}$ and $\tilde{\rho}$ where discovery is possible. For example, we find that a 5$\sigma$ signal can be established for $M_{\tilde{\pi}} \alt 495$ GeV ($M_{\tilde{\rho}} \alt 1650$ GeV). More generally we give the reach of this process for a selection of possible cuts and integrated luminosities.
