  Extended gauge models and the Randall-Sundrum model with extra-dimension
predict the existence of TeV-mass resonances. The LHC potential for a five
sigma level discovery was investigated as described in this document. Final
states containing large invariant mass di-muons from ${Z}^{\prime}$ and the RS1
graviton were studied. The possibility of discriminating between different
${Z}^{\prime}$ model by measuring the muon forward-backward asymmetry was
investigated. The determination of the spin of the resonance is also discussed.
