Performance of the ATLAS global transverse-momentum triggers at $\sqrt{s}$ = 8 TeV
The global transverse momentum triggers of the ATLAS experiment at the CERN Large Hadron Collider are designed to select collision events with non-interacting particles passing through the detector and events with a large amount of outgoing momentum transverse to the beam axis. [...]

Studies of radial distortions of the ATLAS Inner Detector
The measurement of the absolute momentum scale of charged particles provided by the ATLAS inner detector is affected by biases related to geometrical deformations which are not well constrained by the track-based alignment procedure. [...]

Training and validation of the ATLAS pixel clustering neural networks
The high centre-of-mass energy of the LHC gives rise to dense environments, such as the core of high-pT jets, in which the charge clusters left by ionising particles in the silicon sensors of the pixel detector can merge, compromising the tracking and vertexing efficiency. [...]

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.
