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 WW, WZ, and WH, 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 particle χ˜1 0, wino-like particles with masses up to 870 and 960 GeV are excluded in the cases of χ˜2 0→Zχ˜1 0 and χ˜2 0→Hχ˜1 0, respectively, and higgsino-like particles are excluded between 300 and 650 GeV. © 2022 The Author(s)Elsevier B.V.2023Articlehttps://rdlopen.rawdatalibrary.net/r/ebyu/12092https://doi.org/10.1016/j.physletb.2022.1374600370-2693enPhysics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physicsinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/12092
