title: "X-section U.L. 1" of "Search for pair-produced higgsinos decaying via Higgs or $Z$ bosons to final states containing a pair of photons and a pair of $b$-jets with the ATLAS detector"

description: Observed and expected limits on the pure higgsino cross-section at 95% CL assuming B(χ̃<sup>0</sup><sub>1</sub> → hG̃ )=100% for different χ̃<sup>0</sup><sub>1</sub> masses, obtained by a statistical combination of the three signal regions SR1h, SR1Z and SR2. The inner and outer bands indicate the 1σ and 2σ variation on the expected limit respectively.
description: A search is presented for the pair production of higgsinos $\tilde{\chi}$ in gauge-mediated supersymmetry models, where the lightest neutralinos $\tilde{\chi}_1^0$ decay into a light gravitino $\tilde{G}$ either via a Higgs $h$ or $Z$ 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 $\sqrt{s} =13\,\mathrm{TeV}$. It targets final states in which a Higgs boson decays into a photon pair, while the other Higgs or $Z$ boson decays into a $b\bar{b}$ 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 $b\bar{b}$ mass with the mass of the Higgs or $Z$ 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 $320\,\mathrm{GeV}$ are excluded, assuming a branching fraction of 100% for $\tilde{\chi}_1^0\rightarrow h\tilde{G}$. This analysis excludes higgsinos with masses of $130\,\mathrm{GeV}$ for branching fractions to $h\tilde{G}$ as low as 36%, thus providing complementarity to previous ATLAS searches in final states with multiple leptons or multiple $b$-jets, targeting different decays of the electroweak bosons.

title: "Exclusion contour 3" of "Search for pair-produced higgsinos decaying via Higgs or $Z$ bosons to final states containing a pair of photons and a pair of $b$-jets with the ATLAS detector"

description: Observed and expected 95% CL limits on the pure-higgsino branching fraction to B(χ̃<sup>0</sup><sub>1</sub> → hG̃ ) as a function of the higgsino mass m(χ̃<sup>0</sup><sub>1</sub>) assuming it decays via either χ̃<sup>0</sup><sub>1</sub>→ hG̃ or χ̃<sup>0</sup><sub>1</sub>→ ZG̃. Limits are obtained by performing a statistical combination of the three signal regions SR1h, SR1Z and SR2. The ± 1σ variation on the expected limit is shown. The dotted lines indicate the observed limit obtained by a variation of theoretical prediction for the neutralino production cross-section by ±1 σ. Values of B(χ̃<sup>0</sup><sub>1</sub> → hG̃ ) larger than the observed 95% CL limit are excluded, as indicated by the hatched area.

title: "Distribution 8" of "Search for pair-produced higgsinos decaying via Higgs or $Z$ bosons to final states containing a pair of photons and a pair of $b$-jets with the ATLAS detector"

description: Numbers of signal and background events in the signal regions. The respective background estimation techniques are applied. The background category "h (other)" includes events originating from VBF, Vh, ggF, thq, thW and bb̄h, all subdominant in this signature. The different backgrounds are stacked to add up to the total Standard Model prediction in each bin. The predicted yields for signal benchmark models of varying χ̃<sup>0</sup><sub>1</sub> mass are also plotted (not stacked), assuming B(χ̃<sup>0</sup><sub>1</sub> → hG̃ )=100% and a χ̃<sup>0</sup><sub>1</sub> mass of 130 or 200 GeV.
The statistical and systematic uncertainties are indicated by the shaded areas in the top plot. The bottom panel shows the statistical significance [Ref] of the difference between the SM prediction and the observed data in each region.
