 STGC ASSEMBLING AND TESTING IN CHILE FOR THE ATLAS MUON SPECTROMETER / Rojas, Rimsky Alejandro (Universidad Tecnica Federico Santa Maria) /ATLAS Collaboration The forthcoming luminosity upgrade of LHC will increase the expected background rate in the forward region of the ATLAS Muon Spectrometer. The most important upgrade project for the ATLAS is the replacement of the present Small Wheel by the so-called New Small Wheel (NSW). [...] ATL-PHYS-SLIDE-2019-051.- Geneva : CERN, 2019 - 1 p.

 Combination of searches for invisible Higgs boson decays with the ATLAS detector / Dreyer, Sascha Simon (Kirchhoff-Institut f\"{u}r Physik) /ATLAS Collaboration The Standard Model (SM) predicts invisible decays of the Higgs Boson via the H->ZZ*->4$\nu$ channel with a branching ratio of ~$10^{-3}$, too small to be testable at the LHC. Several extensions of the SM predict invisible decays of the Higgs to Dark Matter particles. [...] ATL-PHYS-SLIDE-2019-050.- Geneva : CERN, 2019 - 1 p.

 In situ measurements of the ATLAS Jet Energy Scale using 13 TeV pp data / Camarero Munoz, Daniel (Physics Department, Universidad Autonoma de Madrid) /ATLAS Collaboration The quarks and gluons produced in proton-proton collisions form collimated sprays of particles, known as jets. Jets are produced with large cross-sections, and so a precise understanding of the ATLAS detector's response to these objects improves the quality of physics analyses.

 A High-Granularity Timing Detector for the Phase-II upgrade of the ATLAS Calorimeter system: detector concept, description and R&D and first beam test results / Lund-Jensen, Bengt (Royal Institute of Technology (KTH)) /ATLAS Collaboration The increase of the particle flux (pile-up) at the HL-LHC with luminosities of L ≃ 7.5 × 10^34 cm−2 s-1 will have a severe impact on the ATLAS detector reconstruction and trigger performance. The end-cap and forward region where the liquid Argon calorimeter has coarser granularity and the inner tracker has poorer momentum resolution will be particularly affected.

 Module and System Test Development for the Phase-2 ATLAS ITk Pixel Upgrade / Flick, Tobias (Bergische Universitaet Wuppertal) /ATLAS Collaboration In the high luminosity era of the Large Hadron Collider, the instantaneous luminosity is expected to reach unprecedented values, resulting in about 200 proton-proton interactions in a typical bunch crossing. To cope with the resulting increase in occupancy, bandwidth and radiation damage, the ATLAS Inner Detector will be replaced by an all-silicon system, the Inner Tracker (ITk).

 Missing Transverse Momentum Significance For Full Run 2 using 13 TeV pp data / O'neill, Aaron Paul (University of Oxford, Particle Physics) /ATLAS Collaboration The calculation of missing transverse momentum (ETmiss) has been and will continue to be vital for physics analyses at the ATLAS experiment. Quantifying the momentum imbalance of the event gives physicists the ability to identify non-interacting standard model particles, such as neutrinos, and to search for signatures indicating the presence of physics beyond the Standard Model.

 Observation of electroweak WZjj production at $\sqrt{s} = 13$ TeV with the ATLAS detector / Portales, Louis Adrien Paul (LAPP, Univ. Grenoble Alpes, Univ. Savoie Mont Blanc, CNRS/IN2P3, Annecy) /ATLAS Collaboration This poster presents the observation of electroweak $W^{\pm}Zjj$ (WZjj-EW) production, using 36.1 fb$^{-1}$ of data collected with the ATLAS detector. The analysis focuses on the fully leptonic $\ell\ell\ell\nu jj$ ($\ell = e,\mu$) final state, observed with a significance of $5.3$ standard deviations.

 Muon Reconstruction Performance at ATLAS in Run-II​ / Bergsten, Laura Jean (Brandeis University, Department of Physics) /ATLAS Collaboration Muon reconstruction and identification play a fundamental role in many analyses of central importance in the LHC Run- II Physics program. The algorithms and the criteria used in ATLAS for the reconstruction and identification of muons with transverse momentum from a few GeV to the TeV scale will be presented.

 Characterization of front-end electronics for the High Granularity Timing Detector in ATLAS / Agapopoulou, Christina (LAL, Univ. Paris-Sud, IN2P3/CNRS, Universite Paris-Saclay) /ATLAS Collaboration The High Granularity Timing Detector (HGTD) is a proposed silicon detector for the forward region of the ATLAS detector in the High Luminosity LHC. It's high granularity and excellent timing resolution open new possibilities in the particle reconstruction, physics analysis and luminosity measurement at the HL-LHC..
