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 s=7\sqrt{s} = 7 TeV and assuming an integrated luminosity of 1 fb1^{-1}. A phenomenological Lagrangian is adopted to evaluate the cross section of a pair of colored vector bosons (coloron, ρ~\tilde{\rho}) decaying into four colored scalar resonances (hyper-pion, π~\tilde{\pi}), which then decay into eight gluons. We include the dominant physics background from the production of 8g8g, 7g1q7g1q, 6g2q6g2q, and 5g3q5g3q. We find an abundance of signal events and that realistic cuts reduce the background enough to establish a 5σ5\sigma signal for mπ~\alt220m_{\tilde{\pi}} \alt 220 GeV or mρ~\alt733m_{\tilde{\rho}} \alt 733 GeV.
