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 root s = 7 TeV and 8 TeV at the LHC, with integrated luminosities of up to 5.3 and 4.1 fb(-1), 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/(M) over bar (Pl) is 0.10 (0.05). These are the most stringent limits to date. (C) 2013 CERN. Published by Elsevier B.V. All rights reserved.
