A search for narrow resonances at high mass in the dimuon and dielectron
channels has been performed by the CMS experiment at the CERN LHC, using pp
collision data recorded at sqrt{s}=7 TeV. The event samples correspond to an
integrated luminosity of 1.1 fb^{-1}. Heavy dilepton resonances are predicted
in theoretical models with extra gauge bosons (Z') or as Kaluza-Klein graviton
excitations (G_{KK}) in the Randall-Sundrum model. Upper limits on the
inclusive cross section of Z'(G_{KK}) to l+l- relative to Z to l+l- are
presented. These limits exclude at 95 % confidence level a Z' with
standard-model-like couplings below 1940 GeV, the superstring-inspired Z_{psi}
below 1620 GeV, and, for values of the coupling parameter k/M_{Pl} of 0.05
(0.1), Kaluza--Klein gravitons below 1450 (1780)GeV.Comment: 3 pages, 5 figures, XXXI Physics In Collision 2011 Proceeding
