Abstract

Supersymmetry (SUSY) is an extension of the Standard Model (SM), and its searches are a central part of ATLAS physics program. In this proceeding, the most recent result in searches of chargino ( ˜χ± 1 ) and neutralino ( ˜χ0 2) production where ˜χ± 1 decays in a W boson and the lightest and stable SUSY particle ( ˜χ0 1), while ˜χ0 2 decays in the lightest SUSY particle and a SM Higgs boson is reported. The search was based on the analysis of 36.1 fb−1 pp collision data recorded by the ATLAS experiment at √s = 13 TeV. Fully hadronic, semileptonic, diphoton, and multilepton (electrons, muons) final states with missing transverse momentum are considered in this search. Higgs bosons in the final state are identified by either two jets originating from bottom quarks (h → bb−), two photons (h → γγ), or leptons from the decay modes h → WW, h → ZZ or h → τ τ . As no SUSY signal was observed, the confidence level limits on charginos and neutralinos masses in the context of simplified SUSY models are reported.
