“…For example, in the process qq → g ⋆ n g ⋆ n , the presence of the g ⋆ 2n exchange is crucial with its mass 2nµ and its coupling as dictated by the KK Yang-Mills theory. This is a new example of tree-unitarity for a class of massive vector boson theories other than the known spontaneously broken gauge theories [17].…”

We consider an asymmetric string compactification scenario in which the SM gauge bosons can propagate into one TeV −1 -size extra compact dimension. These gauge bosons have associated 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 Large Hadron Collider energy. In the case of dijet final states with very high p T , 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-p T effect is not as dramatic for the direct production of a single on-shell g ⋆ , which subsequently decays into q-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. *

“…S-matrix unitarity restricts the ZZV couplings uniquely to their SM values at asymptotically high energies [16]. This requires that the couplings f V i possess a momentum dependence which ensures that the f V i (q 2 1 , q 2 2 , P 2 ) vanish for any momenta much larger than M Z .…”

A detailed analysis of ZZ production at the upgraded Fermilab Tevatron and the CERN Large Hadron Collider is presented for general ZZZ and ZZγ couplings. Deviations from the Standard Model gauge theory structure for each of these can be parameterized in terms of two form factors which are severely restricted by unitarity at high energy. Achievable limits on these couplings are shown to be a dramatic improvement over the limits currently obtained by e +
