Abstract: A search for dark matter particles is performed using events with a pair of W bosons and large missing transverse momentum. Candidates are selected by requiring one or two leptons (electrons or muons) from the W boson decays. The analysis is based on proton-proton collision data taken at a center-of-mass energy of 13 TeV by the CMS experiment at the LHC and corresponding to an integrated luminosity of 137 fb−1. No significant excess over the expected standard model background is observed in the semi- and di-leptonic final states of the W+W− decay channel. Limits are set on dark matter production in the context of a dark Higgs simplified model, with a dark Higgs mass above the W+W− mass threshold. | ||
