Search for direct pair production of a chargino and a neutralino decaying to the 125 GeV Higgs boson in root s=8 TeV pp collisions with the ATLAS detector
2015
Abstract
A search is presented for the direct pair production of a chargino and a neutralino pp RIGHTWARDS ARROW ~χ +- 1 ~χ 0 2 , where the chargino decays to the lightest neutralino and the W boson, ~χ +- 1 RIGHTWARDS ARROW ~χ0 1 (W+- RIGHTWARDS ARROW +- ν), while the neutralino decays to the lightest neutralino and the 125 GeV Higgs boson, ~χ 0 2 RIGHTWARDS ARROW ~χ0 1 (h RIGHTWARDS ARROW bb/γ γ / +- νqq). The final states considered for the search have large missing transverse momentum, an isolated electron or muon, and one of the following: either two jets identified as originating from bottom quarks, or two photons, or a second electron or muon with the same electric charge.
