Search for high-mass resonances in the dilepton final state in p-p collisions at $\sqrt{s}$ = 13 TeV with 2016 and 2017 data sets with the CMS detector

A search for new high-mass resonances decaying into electron or muon pairs has been performed using data collected at a centre-of-mass energy of 13 TeV by the CMS experiment at the CERN LHC in 2016, corresponding to an integrated luminosity of 36 fb$^{-1}$; preliminary results using 2017 data, corre...

Descripción
Sumario:A search for new high-mass resonances decaying into electron or muon pairs has been performed using data collected at a centre-of-mass energy of 13 TeV by the CMS experiment at the CERN LHC in 2016, corresponding to an integrated luminosity of 36 fb$^{-1}$; preliminary results using 2017 data, corresponding to 43 fb$^{-1}$ are shown. Upper limits on the product of production cross section and branching fraction are calculated in a model-independent manner which permits the interpretation of the limits in all models predicting a narrow dielectron or dimuon resonance structure, including the Sequential Standard Model, a Superstring inspired model or the Randall-Sundrum Model with the Kaluza-Klein graviton. Limits are set on the masses of hypothetical particles that could appear in new-physics scenarios.
