| Abstract: An updated search for heavy narrow resonances decaying to muon or electron pairs using the CMS detector is presented. Data samples from pp collisions at $\sqrt{s}$ = 7 TeV and 8 TeV at the LHC, with integrated luminosities of up to 5.3 and 4.1 inverse femtobarns, respectively, are combined. No evidence for a heavy narrow resonance is observed. The analysis of the combined data sets excludes, at 95% confidence level, a Sequential Standard Model Z'$_{SSM}$ resonance lighter than 2590 GeV, a superstring-inspired Z'$_{\psi}$ lighter than 2260 GeV, and Kaluza-Klein gravitons lighter than 2390 (2030) GeV, assuming that the coupling parameter $k/\bar{M}_{Pl}$ is 0.10 (0.05). These are the most stringent limits to date. | ||
