Search for electroweak production of charginos and neutralinos at s=13TeV in final states containing hadronic decays of WW, WZ, or WH and missing transverse momentum

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 13TeVcollected with the CMS detector at the LHC, corresponding to an integrated luminosity of 137fb...

Descripción
Sumario: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 13TeVcollected with the CMS detector at the LHC, corresponding to an integrated luminosity of 137fb−¹. The search considers final states with large missing transverse momentum and pairs of hadronically decaying bosons WW, WZ, and WH, where His 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~±1and χ~⁰₂, and mass-degenerate higgsino-like supersymmetric particles χ~±1, χ~⁰₂, and χ~⁰₃. In the limit of a nearly-massless lightest supersymmetric particle χ~⁰₁, wino-like particles with masses up to 870 and 960 GeV are excluded in the cases of χ~⁰₂ → χ~⁰₁ and χ~⁰₂ → χ~⁰₁ respectively, and higgsino-like particles are excluded between 300 and 650 GeV.
