 ATLAS LAr Calorimeter Performance in LHC Run-2 and Electronics Upgrades for next Runs / McKay, Madalyn Ann (Southern Methodist University, Department of Physics) /ATLAS Collaboration Liquid argon (LAr) sampling calorimeters are employed by ATLAS for all electromagnetic calorimetry in the pseudo-rapidity region |η| < 3.2, and for hadronic and forward calorimetry in the region from |η| = 1.5 to |η| = 4.9. In the LHC Run-2 about 150fb-1 of data at a center- of-mass energy of 13 TeV have been recorded. [...] ATL-LARG-SLIDE-2019-039.- Geneva : CERN, 2019 - 30 p.

 The ATLAS DAQ System from Run 2 to HL-LHC / Panduro Vazquez, Jose Guillermo (Department of Physics, Royal Holloway and Bedford New College) ; ATLAS Collaboration /ATLAS Collaboration The ATLAS DAQ System will undergo a series of upgrades in order to be ready for the challenges of HL-LHC. This overview talk will describe the evolution of the system carried out for Run 2, before drawing on wider technological trends to discuss and motivate the introduction of the FELIX platform for Run 3.

 Jet Measurements in Heavy Ion Collisions with ATLAS  / Sickles, Anne Marie (University of Illinois at Urbana-Champaign) /ATLAS Collaboration Highly energetic jets produced in ultra-relativistic nuclear collisions are considered to be direct probes to study the properties of the hot and dense QCD matter created in these collisions. Measurements of the inclusive jet yield and fragmentation functions of jets into charged particles in Pb+Pb collisions are sensitive to the strength and mechanism of jet quenching.

 Photon and photon+jet probes of small and large collision systems with ATLAS / Perepelitsa, Dennis (University of Colorado Boulder) /ATLAS Collaboration Measurements of photon and photon+jet production can shed light into the initial- and final-state interactions in collisions involving large nuclei. The ATLAS detector at the Large Hadron Collider measures prompt isolated photons over a broad kinematic range with barrel and endcap liquid argon electromagnetic calorimeters.

 Top Scicomm: Communicating ATLAS top physics results to the public / Nellist, Clara (Georg-August-Universitat Goettingen, II. Physikalisches Institut) ; Anthony-Kittelsen, Katarina-Amelia (INFN Gruppo Collegato di Udine and Universita' di Udine, Dipartimento di Chimica, Fisica e Ambiente) ; Goldfarb, Steven (ARC Centre of Excellence in Particle Physics at the Terascale, School of Physics, The University of Melbourne) ; Mehlhase, Sascha (Fakultaet fuer Physik, Ludwig-Maximilians-Universitaet Muenchen) ; Shaw, Kate (University of Sussex) ; Thais, Savannah Jennifer (Yale University) ; Jarvis-Ward , Emma (INFN Gruppo Collegato di Udine and Universita' di Udine, Dipartimento di Chimica, Fisica e Ambiente) /ATLAS Collaboration An essential component of the long-term success of scientific research is communicating the results and methodology to the wider public. Social media is a vital new tool for this endeavour. [...] ATL-OREACH-SLIDE-2019-035.- Geneva : CERN, 2019 - 1 p.

 Test Beam Studies for the upgrade of the ATLAS Tile Calorimeter read-out electronics for the HL-LHC / Carrio Argos, Fernando (Univ. of Valencia and CSIC (ES)) /ATLAS Collaboration The High Luminosity Large Hadron Collider (HL-LHC) is expected to start in 2026 the delivery of 3-4/ab of proton-proton collisions with up to 200 collisions per proton bunch crossing. The electronics of the ATLAS Tile Calorimeter has to be upgraded to cope with longer latencies of up to 35 µs needed by the trigger system at such high pileup levels and higher read-out rates.

 Studies of the response of the ATLAS Tile Calorimeter to beams of particles at the CERN test beams facility / Zakareishvili, Tamar (High Energy Physics Institute of Tbilisi State University) /ATLAS Collaboration The Large Hadron Collider (LHC) Phase II upgrade aims to increase the accelerator instantaneous luminosity by a factor of 10. Due to the expected higher radiation levels, aging of the current electronics and to provide the capability of coping with longer latencies of up to 35 µs needed by the trigger system at such high pileup levels, a new readout system of the ATLAS Tile Calorimeter (TileCal) is needed.

 Light-by-light scattering in lead-lead collisions in the ATLAS experiment / Ogrodnik, Agnieszka (AGH University of Science and Technology, Faculty of Physics and Applied Computer Science, Krakow) /ATLAS Collaboration First direct evidence of light-by-light scattering ($\gamma\gamma \rightarrow \gamma\gamma$) was reported in 2017 by the ATLAS experiment, based on 0.48 nb$^{-1}$ of 2015 Pb+Pb collision data at $\sqrt{s_{\textrm{NN}}}=5.02$ TeV. A total of 13 events was found in the signal region with a background expectation of 2.6$\pm$0.7 events. [...] ATL-PHYS-SLIDE-2019-031.- Geneva : CERN, 2019 - 10 p.

 Heavy Ions from ATLAS Experiment / Santos, Helena (Laboratorio de Instrumenta\c{c}\~ao e Fisica Experimental de Particulas - LIP, Lisboa) /ATLAS Collaboration The experimental data collected by the ATLAS experiment during the Run 2 LHC runs provide a broad physics program to probe and characterize the Quark Gluon Plasma created in these collision systems. The large acceptance and high granularity of the detector is well suited to perform detailed analyses on bulk phenomena, electroweak probes, quarkonia, charged particles and jets.
