Search for pair-produced higgsinos decaying via Higgs or ???? bosons to final states containing a pair of photons and a pair of ????-jets with the ATLAS detector

Original language description

A search is presented for the pair production of higgsinos ???? in gauge-mediated supersymmetry models, where the lightest neutralinos ????0 1 decay into a light gravitino ???? in association with either a Higgs ℎ or a ???? boson. The search is performed with the ATLAS detector at the Large Hadron Collider using 139 fb-1 of proton-proton collisions at a centre-of-mass energy of SQUARE ROOT???? = 13 TeV. It targets final states in which a Higgs boson decays into a photon pair, while the other Higgs or ???? boson decays into a ????̄???? pair, with missing transverse momentum associated with the two gravitinos. Search regions dependent on the amount of missing transverse momentum are defined by the requirements that the diphoton mass should be consistent with the mass of the Higgs boson, and the ????̄???? mass with the mass of the Higgs or ???? boson. The main backgrounds are estimated with data-driven methods using the sidebands of the diphoton mass distribution. No excesses beyond Standard Model expectations are observed and higgsinos with masses up to 320 GeV are excluded, assuming a branching fraction of 100% for ???? 0 1 RIGHTWARDS ARROW ℎ ????. This analysis excludes higgsinos with masses of 130 GeV for branching fractions to ℎ ???? as low as 36%, thus providig complementarity to previous ATLAS searches in final states with multiple leptons or multiple ????-jets, targeting different decays of the electroweak bosons.
