Publisher: | Elsevier | Abstract: | 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 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 & chi;⠂& PLUSMN; 1 and & chi;⠂02, and mass-degenerate higgsino-like supersymmetric particles & chi;⠂& PLUSMN;1,& chi;⠂02, and & chi;⠂03. In the limit of a nearly-massless lightest supersymmetric particle & chi;⠂01, wino-like particles with masses up to 870 and 960 GeV are excluded in the cases of & chi;⠂02 & RARR; Z & chi;⠂01 and & chi;⠂02 & RARR; H & chi;⠂01, respectively, and higgsino-like particles are excluded between 300 and 650 GeV. & COPY; 2022 The Author(s).
