Discovering Colorons at the Early Stage LHC

TL;DR

This paper explores the potential to discover massive hyper-gluons, called colorons, at the early LHC runs by analyzing specific decay channels and backgrounds, predicting detectable signals for certain mass ranges.

Contribution

It introduces a phenomenological model for hyper-gluon production and decay, providing predictions for early LHC data analysis and potential discovery of colorons.

Findings

Signal events are abundant for the considered processes.

Realistic cuts can suppress backgrounds sufficiently.

A 5σ discovery is possible for certain mass ranges.

Abstract

We investigate the prospects for the discovery of massive hyper-gluons using data from the early runs of the CERN Large Hadron Collider with $\sqrt{s} = 7$ TeV and assuming an integrated luminosity of 1 fb$^{-1}$. A phenomenological Lagrangian is adopted to evaluate the cross section of a pair of colored vector bosons (coloron, $\tilde{\rho}$) decaying into four colored scalar resonances (hyper-pion, $\tilde{\pi}$), which then decay into eight gluons. We include the dominant physics background from the production of $8g$, $7g1q$, $6g2q$, and $5g3q$. We find an abundance of signal events and that realistic cuts reduce the background enough to establish a $5\sigma$ signal for $m_{\tilde{\pi}} \alt 220$ GeV or $m_{\tilde{\rho}} \alt 733$ GeV.
