Özet
This Letter presents a search for direct production of charginos and neutralinos via electroweak interactions. The results are based on data from proton-proton collisions at a center-of-mass energy of 13 TeV collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 137 fb− 1. The search considers final states with large missing transverse momentum and pairs of hadronically decaying bosons W W, W Z, and W H, where H is the Higgs boson. These bosons are identified using novel algorithms. No significant excess of events is observed relative to the expectations from the standard model. Limits at the 95% confidence level are placed on the cross section for production of mass-degenerate wino-like supersymmetric particles χ˜ 1±and χ˜ 2 0, and mass-degenerate higgsino-like supersymmetric particles χ˜ 1±, χ˜ 2 0, and χ˜ 3 0. In the limit of a nearly-massless lightest supersymmetric …
