Search for high-mass resonances decaying into dilepton final state at 13 TeV with CMS

A search for new high-mass resonances decaying into electron or muon pairs is performed using the full dataset obtained from proton-proton collisions at 13 TeV. The search exploits data collected by the CMS experiment in 2016, corresponding to an integrated luminosity of 36 $\mathrm{fb^{-1}}$. No significant deviations are observed from the standard model expectation. Upper limits on the product of a new resonance production cross section and branching fraction to dileptons are calculated in a model-independent manner. A lower mass limit is set at 95 % confidence level for new spin-1 resonance arising in the sequential standard model and grand unified theory models, and spin-2 Kaluza-Klein graviton arising in the Randall-Sundrum model of extra dimensions.
