The search is conducted using an integrated luminosity of 140 fb$^{-1}$ of proton-proton collision data at a centre-of-mass energy of 13 TeV recorded with the ATLAS detector at the Large Hadron Collider. The search is performed over the mass range 170 $\\leq$$m_{X}$$\\leq$ 1000 GeV and 15 $\\leq$$m_{S}$$\\leq$ 500 GeV. Parameterised neural networks are used to enhance the signal purity and to achieve continuous sensitivity in a domain of the ($m_{X}$, $m_{S}$) plane. No significant excess above the expected background is found and 95% CL upper limits are set on the cross section times branching ratio, ranging from 39 fb to 0.09 fb. The largest deviation from the background-only expectation occurs for ($m_{X}$, $m_{S}$) = (575, 200) GeV with a local (global) significance of 3.5 (2.0) standard deviations.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.151649.v1/t1","@type":"Dataset","description":"Number of events for the 2 b-jet process category obtained from a background-only fit to data in the signal region...","name":"2 b-jet selection data"},{"@id":"https://doi.org/10.17182/hepdata.151649.v1/t2","@type":"Dataset","description":"Number of events for the 1 b-jet process category obtained from a background-only fit to data in the signal region...","name":"1 b-jet selection data"},{"@id":"https://doi.org/10.17182/hepdata.151649.v1/t3","@type":"Dataset","description":"Expected and observed 95% CL upper limits on the signal cross section times the branching ratio of X \u2192 SH...","name":"Summary of 95% CL Limits"},{"@id":"https://doi.org/10.17182/hepdata.151649.v1/t4","@type":"Dataset","description":"Local observed significance for signal discovery at different (mX, mS).
