“…Before jets can be used in analyses their interaction with the detector must be well understood and properly calibrated. This poster will describe the calibration of the $\textit{in situ}$ jet energy scale (JES) for large-$R$ jets (anti-$k_{t}$ $R = 1.0$) in the ATLAS experiment, as measured via the $\gamma+$jet direct $p_{\mathrm{T}}$ balance method from 35.7 fb$^{-1}$ of 2015-2016 data. …”

“…Such b-hadron identification is a particularly challenging task, owing to the relatively short decay length of such b-hadrons and difficulties identifying hadronic jets, and current flavour tagging algorithms are often not tuned to identify such b-hadron decays. This poster presents new developments for soft b-hadron tagging techniques based either on the presence of jets composed only of tracks, or on the identification of secondary vertices from the b-hadron decay seeded without requiring the presence of a jet. …”

“…The high number of pile-up interactions was one of the major challenges faced during Run 2 and a continuous effort was needed to improve the pile-up rejection and to keep the trigger rate reasonable. This poster presents the techniques used to improve the Run 2 transverse missing momentum trigger performance, the full Run 2 performance and an outlook on possible improvements using tracking for Run 3.…”

“…Fiducial differential cross section measurements are an important part of the efforts to precisely measure the Higgs boson properties, providing model-independent measurements of kinematic and event observables. This poster presents the H to yy fiducial and differential cross section analysis using the full Run-2 data set taken between 2015 and 2018 at the ATLAS experiment. …”

“…The analysis utilizes a novel neural network to estimate the large QCD backgrounds, and employs analysis categorizations to improve the sensitivity to di-Higgs production. This poster will present the analysis strategy and the latest result of the observed (expected) upper limits on the SM HH production cross-section and the constraint on the Higgs self-coupling at a 95% confidence in this analysis.…”
