Discovering Colorons at the Early Stage LHC


الملخص بالإنكليزية

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 $5sigma$ signal for $m_{tilde{pi}} alt 220$ GeV or $m_{tilde{rho}} alt 733$ GeV.
