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.11 pages, 10 figures, Talk given at "Advanced Studies Institute - Physics At LHC" Conference, Prague, Czech Republic, 6-12 July 2003.
