| Abstract: A search for physics beyond the standard model in final states with an electron, or muon, and missing transverse momentum is presented. The analysis uses data from proton-proton collisions at 13 TeV center-of-mass energy, collected with the CMS detector at the LHC in 2016, 2017, and 2018 corresponding to a total integrated luminosity of 137 fb$^{-1}$. No significant deviation from the standard model prediction is observed. Model-independent limits are set on the production cross section of W' bosons decaying into lepton plus neutrino final states. This analysis also sets limits on the parameters of other new physics models. The best exclusion limit obtained is 5.7 TeV at 95% confidence level on the mass of a sequential standard model W' boson with standard-model-like couplings and comes from combining electron and muon decay channels. Results on oblique electroweak parameters, in particular on the W parameter, are also presented, for the first time using LHC data. | ||
