 Performance of mass-decorrelated jet substructure observables for hadronic two-body decay tagging in ATLAS Mass-decorrelated jet substructure observables have the potential to increase the sensitivity of searches for new physics in final states with high-$p_{\mathrm{T}}$ hadronically decaying resonances, both by minimising the sculpting of background jet mass distributions and enabling more robust background estimation.

 Track assisted techniques for jet substructure The substructure of large-radius (large-$R$) jets provides an important handle to discriminate hadronic decays such as $W\to q{q}$, $H\to bb$, $H\to W(q{q})W^*(q{q})$, and $t\to W(q{q})b$ from QCD multijet backgrounds.

 Impact of Pile-up on Jet Constituent Multiplicity in ATLAS One of the biggest challenges facing jet constituent multiplicity measurements is contamination from extraneous sources of soft radiation, such as pile-up.

 Impact of theory uncertainties related to Higgs boson production in the $H\rightarrow Z Z^{*}\rightarrow 4l$ and the $t\bar{t}H$ channels with the ATLAS detector at the HL-LHC A study is presented on the impact of theory uncertainties related to the Higgs boson production in the $H \rightarrow Z Z^{*} \rightarrow 4l$, $t\bar{t}H,H\rightarrow \gamma\gamma$ and $t\bar{t}H$ multi-leptons channels, using 14 TeV proton-proton collisions at the High Luminosity LHC with 3000 $fb^{-1}$.
