Abstract (data abstract)
CERN-LHC. Study of high-mass lepton pairs (electron-positrons or muon-antimuons) produced in proton-proton collisions at a centre of mass energy of 7 TeV using data samples with integrated luminsoity of 4.9 fb-1 in the electron channel and 5.0 fb-1 in the muon channel. The results are interpreted in the search for the heavy boson resonances: heavy neutral Zprime gauge bosons, Randall-Sundrum gravitons, Z* bosons, techni-mesons, Kaluza-Klein Z/gamma bosons and bosons predicted by Torsion models.
