We consider an asymmetric string compactification scenario in which the standard model (SM) gauge bosons can propagate into one TeV^\mathrm\ensuremath-1-sized extra compact dimension. These gauge bosons have associated Kaluza-Klein (KK) excitations that present additional contributions to the SM processes. We calculate the effects that the KK excitations of the gluons, g★'s, have on multijet final-state production in proton-proton collisions at the CERN Large Hadron Collider energy. In the case of dijet final states with very high pT, the KK signal due to the exchanges of the g★'s is several factors greater than the SM background for compactification scales as high as about 7 TeV. The high-pT effect is not as dramatic for the direct production of a single on-shell g★, which subsequently decays into q\ensuremath-q pairs, where the KK signal significantly exceeds the SM three-jet background for compactification scales up to about 3 TeV. We also present our results for the four-jet final-state signal from the direct production of two on-shell g★'s.
