The data sample corresponds to an integrated luminosity of approximately 5 fb(-1). The event yields observed in the signal regions are consistent with predictions of the standard model backgrounds, and upper limits on the cross section times branching fraction for a resonance decaying to dileptons are extracted from a shape analysis of the dilepton invariant mass distribution. The resulting mass limits at 95% confidence level are 2330 GeV for the Z' in the Sequential Standard Model, 2000 GeV for the superstring-inspired Z'(psi) resonance, 890 (540) GeV for the Stueckelberg extension Z'(St) the mass parameter epsilon = 0.06 (0.04), and 2140 (1810) GeV for Kaluza-Klein gravitons with the coupling parameter k/(M) over bar (Pl) of 0.10 (0.05). These limits are the most stringent to date.engrestrictedAccessarticle7142-515817900030768010000410.1016/j.physletb.2012.06.051CMSDileptonsResonances
