 Projections for ATLAS Measurements of Bulk Properties of Pb+Pb, $p$+Pb, and $pp$ Collisions in LHC Runs 3 and 4 This note describes expected ATLAS measurements of bulk and flow properties of dense nuclear matter measured in heavy-ion collisions (AA and pA) in LHC Runs 3 and 4.

 Projections for ATLAS Measurements of Jet Modifications in Pb+Pb Collisions in LHC Runs 3 and 4 The primary goal of the heavy ion program at ATLAS is to study the properties of the deconfined, strongly interacting matter, the quark-gluon plasma (QGP).

 Prospects for Measurements of Photon-Induced Processes in Ultra-Peripheral Collisions of Heavy Ions with the ATLAS Detector in the LHC Runs 3 and 4 This note describes results which could be expected for measurements of photon-photon interactions in lead-lead collisions by the ATLAS experiment in the LHC Runs 3 and 4.

 Determination of the parton distribution functions of the proton from ATLAS measurements of differential $W$ and $Z/\gamma^*$ and $t\bar{t}$ cross sections An analysis of ATLAS data on inclusive $W^{\pm}$ and $Z/\gamma^*$ boson production and $t\bar{t}$ production in $pp$ collisions at the LHC is reported.

 Prospects for $H\rightarrow c\bar c$ using Charm Tagging with the ATLAS Experiment at the HL-LHC The expected sensitivity of a search for decays of the Higgs boson into charm quarks is estimated for the ATLAS detector at the HL-LHC, by extrapolating the results obtained using a dataset with an integrated luminosity of $36.1\ \text{fb}^{-1}$ at $\sqrt{s}=13\ \text{TeV}$.

 Jet Mass Resolutions in ATLAS using Run 2 Monte Carlo Simulation The jet mass resolution (JMR) and its uncertainty are amongst the limiting systematic effects for precision measurements and searches for physics beyond the Standard Model.

 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.

 Generalized Numerical Inversion: A Neural Network Approach to Jet Calibration Jets that are reconstructed by the ATLAS detector are corrected to ensure that the reported energy is an unbiased measurement of the particle-level jet energy.

 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.
