Abstract
Many well-established models extending beyond the standard model predict the existence of new heavy neutral bosons that would decay in two leptons. A search for new narrow resonances, generically referred to as Z', in the dielectron and dimuon decay channels has been performed using data collected by the CMS experiment in 2016 from proton-proton collisions at a center-of-mass energy of √s = 13 TeV (corresponding to an integrated luminosity of 13 fb−1) and combining the 2015 13 TeV data (2.9 fb−1) with a previous analysed set of data obtained at √s = 8 TeV (20 fb−1). In the absence of a significant deviation from the standard model predictions, 95% confidence level limits are set on the ratio of the production crosssection times branching fraction for high-mass resonances to that for the Z boson. For several models, lower limits on the resonance mass are derived.
