| Abstract: A combination of several searches for the electroweak production of winos, binos, higgsinos, and sleptons is presented. All searches use proton-proton collision data at $ \sqrt{s}= $ 13 TeV recorded with the CMS detector at the LHC during years 2016-2018. The analyzed data set corresponds to an integrated luminosity of 137 fb$ ^{-1} $. The results are interpreted in simplified models of chargino-neutralino, neutralino, or slepton pair production. In addition to the previously published searches, the combination includes results from an updated version of the search targeting events with two low-momentum leptons and missing transverse momentum. A parametric signal extraction is introduced that enhances the sensitivity to each signal hypothesis, along with a signal selection optimized to search for slepton pair production in models with compressed spectra. In addition to the models previously considered, the results of the combination are interpreted in a scenario where neutralinos and charginos in a mass-degenerate higgsino triplet are produced and decay to SM bosons and a bino-like LSP. The results are consistent with expectations from the standard model. The combination provides a more comprehensive coverage of the model parameter space than the individual searches, and adds sensitivity in the compressed mass parameter regions. | ||
