Studies on the impact of an extended Inner Detector tracker and a forward muon tagger on $W^{\pm}W^{\pm}$ scattering in $pp$ collisions at the High-Luminosity LHC with the ATLAS experiment
The impact of an extended silicon tracker and a forward muon tagger on the measurement of the \ssWW vector boson scattering process is evaluated in proton-proton collisions at $\sqrt{s}$ = 14 TeV at the High-Luminosity Large Hadron Collider. [...]

Electron and photon reconstruction and performance in ATLAS using a dynamical, topological cell clustering-based approach
The electron and photon reconstruction in ATLAS has moved towards the use of a dynamical, topo- logical cell-based approach for cluster building, owing to advancements in the calibration procedure which allow for such a method to be applied. [...]

Prospects for the measurement of the W-boson transverse momentum with a low pileup data sample at $\sqrt{s} = 13$ TeV with the ATLAS detector
The imperfect knowledge of the $W$-boson transverse momentum ($p_T^W$) distribution is likely to be the limiting factor for future measurements of the $W$-boson mass at the Large Hadron Collider. [...]

Impact of Alternative Inputs and Grooming Methods on Large-R Jet Reconstruction in ATLAS
During Run 1 of the LHC, the optimal reconstruction algorithm for large-$R$ jets in ATLAS, characterized in terms of the ability to discriminate signal from background and robust reconstruction in the presence of pileup, was found to be anti-$k_{t}$ jets with a radius parameter of 1.0, formed from locally calibrated topological calorimeter cell clusters and groomed with the trimming algorithm to remove contributions from pileup and underlying event.
