摘要：

Prospects are investigated for the discovery of massive hypergluons using data from the early runs of the Large Hadron Collider. A center of mass energy of 7 TeV and an integrated luminosity of 1 fb(-1) or 5 fb(-1) are assumed. A phenomenological Lagrangian is adopted to evaluate the cross section of a pair of colored vector bosons (colorons, (rho) over tilde) decaying into four colored scalar resonances (hyperpions, (pi) over tilde), which then decay into eight gluons. The dominant eight-jet background from the production of 8g, 7g1q, 6g2q, and 5g3q is included. We find an abundance of signal events and that realistic cuts reduce the background enough to establish a 5 sigma signal for the coloron mass of up to 733 GeV with 1 fb(-1) or 833 GeV with 5 fb(-1).
