Search for chargino and neutralino production in final states with a Higgs boson and missing transverse momentum at $\sqrt{s} = 13$ TeV with the ATLAS detector

The ATLAS collaboration
Phys.Rev., 2018

Abstract (data abstract)
CERN-LHC. A search is presented for the electroweak pair production of a chargino and a neutralino, where the chargino decays to the lightest neutralino and the W boson, while the neutralino decays to the lightest neutralino and the 125 GeV Higgs boson. Fully hadronic, semi-leptonic, and multi-lepton final states with large missing transverse momentum are considered in this search. Higgs bosons in the final state are identified by either two jets identified as originating from bottom quarks, or two photons, or a second electron or muon with the same electric charge. The analysis is based on 36.1 fb$^{-1}$of $\sqrt{s}$=13 TeV proton-proton collision data delivered by the Large Hadron Collider and recorded with the ATLAS detector. Observations are consistent with the Standard Model expectations, and limits are set in the context of a simplified supersymmetric model.
