The Higgs program and open questions in particle physics and cosmology
[arXiv:1905.00382]
The Higgs program is relevant to many of the open fundamental questions in particle physics and cosmology. Thus, when discussing future collider experiments, one way of comparing them is by assessing their potential contributions to progress on these questions. [...]

A search for the production of three massive vector bosons in proton--proton collisions is performed using data at $\sqrt{s}=13\,TeV$ recorded with the ATLAS detector at the Large Hadron Collider in the years 2015--2017, corresponding to an integrated luminosity of $79.8\,\text{fb}^{-1}$. Events with two same-sign leptons $\ell$ (electrons or muons) and at least two reconstructed jets are selected to search for $WWW\to\ell\nu\ell\nu qq$. [...]

Measurement of $K_S^0$ and $\Lambda ^0$ production in $t \bar{t}$ dileptonic events in pp collisions at $\sqrt{s} =$ 7 TeV with the ATLAS detector
[arXiv:1907.10862; CERN-EP-2019-112]
Measurements of $K_S^0$ and $\Lambda ^0$ production in $t\bar{t}$ final states have been performed. They are based on a data sample with integrated luminosity of 4.6 $\mathrm {fb}^{-1}$ from proton–proton collisions at a centre-of-mass energy of 7 TeV, collected in 2011 with the ATLAS detector at the Large Hadron Collider. [...]

Erratum to: Measurements of W and Z boson production in pp collisions at $\sqrt{s}=5.02$ s = 5.02  TeV with the ATLAS detector
[arXiv:1810.08424; CERN-EP-2018-259]
Measurements of fiducial integrated and differential cross sections for inclusive $W^+$ , $W^-$ and Z boson production are reported. They are based on $25.0 \pm 0.5\, \mathrm {pb}^{-1}$ of pp collision data at $\sqrt{s} = 5.02$  TeV collected with the ATLAS detector at the CERN Large Hadron Collider. [...]

Erratum to: Measurement of the W boson polarisation in $t\bar{t}$ t t ¯ events from pp collisions at $\sqrt{s} = 8~\hbox {TeV}$ s = 8 TeV in the lepton + jets channel with ATLAS
[CERN-EP-2016-219; CERN-PH-2016-219; arXiv:1612.02577]
This paper presents a measurement of the polarisation of W bosons from $t\bar{t}$ decays, reconstructed in events with one high- $p_{\text{ T }}$ lepton and at least four jets. Data from pp collisions at the LHC were collected at $\sqrt{s}$ = 8 TeV and correspond to an integrated luminosity of 20.2 fb$^{-1}$ . [...]

Mapping the depleted area of silicon diodes using a micro-focused X-ray beam
[arXiv:1809.02667]
For the Phase-II Upgrade of the ATLAS detector at CERN, the current ATLAS Inner Detector will be replaced with the ATLAS Inner Tracker (ITk). The ITk will be an all-silicon detector, consisting of a pixel tracker and a strip tracker. [...]

Dark Matter Benchmark Models for Early LHC Run-2 Searches: Report of the ATLAS/CMS Dark Matter Forum
[arXiv:1507.00966; FERMILAB-PUB-15-282-CD]
This document is the final report of the ATLAS-CMS Dark Matter Forum, a forum organized by the ATLAS and CMS collaborations with the participation of experts on theories of Dark Matter, to select a minimal basis set of dark matter simplified models that should support the design of the early LHC Run-2 searches. A prioritized, compact set of benchmark models is proposed, accompanied by studies of the parameter space of these models and a repository of generator implementations. [...]

LHC Dark Matter Working Group: Next-generation spin-0 dark matter models
[arXiv:1810.09420; CERN-LPCC-2018-02]
Dark matter (DM) simplified models are by now commonly used by the ATLAS and CMS Collaborations to interpret searches for missing transverse energy ( ETmiss ). The coherent use of these models sharpened the LHC DM search program, especially in the presentation of its results and their comparison to DM direct-detection (DD) and indirect-detection (ID) experiments.
