Discovering Colorons at the Early Stage LHC

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 $m_{\tilde{\pi }}\text{alt}220$ GeV or $m_{\tilde{\rho }}\text{alt}733$ GeV.
