The search is conducted using integrated luminosities of 140 and 59 fb$^{-1}$ of proton-proton collision data at centre-of-mass energies of 13 and 13.6 TeV, respectively, recorded with the ATLAS detector at the LHC. The search is performed over the mass ranges of 170 $\\leq$$m_{X}$$\\leq$ 1000 GeV and 15 $\\leq$$m_{S}$$\\leq$ 500 GeV. No significant excess over the Standard Model background prediction is observed and limits at 95% confidence level are set on the product of cross section and branching fraction for the process $X \\rightarrow S (\\rightarrow b \\bar{b})H ( \\rightarrow \u03b3\u03b3)$ at 13 TeV, ranging from 9 fb to 0.06 fb.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.165817.v1/t1","@type":"Dataset","description":"Cutflow efficiencies for some generated MC signal sample for the Run-2 dataset.
