Search for TeV-scale bosons in the dimuon channel at the LHC

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 $Z^{\mathrm{\prime }}$ and the RS1 graviton were studied. The possibility of discriminating between different $Z^{\mathrm{\prime }}$ model by measuring the muon forward-backward asymmetry was investigated. The determination of the spin of the resonance is also discussed.
