QCD and the Search for Exotic Physics / Pacey, Holly Ann (Cavendish Laboratory, University of Cambridge) /ATLAS Collaboration
Signature based searches for new physics probe the full range of the collision energy spectrum probed by the Large Hadron Collider. Often the most numerous decays,and thus those with the highest reach in new particle mass, occur in channels with at least one hadronic object and therefore requires control and understanding of the corresponding QCD background.

The ATLAS Tile Calorimeter performance in the LHC Run-2 and its upgrade towards the High-Luminosity LHC / Nibigira, Emery (Laboratoire de Physique de Clermont-Ferrand (LPC), Universite Clermont Auvergne, CNRS/IN2P3, Clermont-Ferrand, France) /ATLAS Collaboration
The Tile Calorimeter (TileCal) is a sampling hadronic calorimeter covering the central region of the ATLAS experiment. TileCal uses steel as absorber and plastic scintillators as active medium. [...]

QCD issues in searches for Supersymmetry with the ATLAS detector / Magerl, Veronika (Albert-Ludwigs-Universitaet Freiburg) /ATLAS Collaboration
Despite the absence of experimental evidence, weak-scale supersymmetry remains one of the best motivated and studied Standard Model extensions. Searches for weak-scale supersymmetry interact with QCD in many ways: QCD scaling rules are used in background estimation techniques; jet sub-structure is exploited for separating signal and background; signal cross sections rely on higher-order calculations and resummation.

Measurement of jet substructure observables using the ATLAS detector / Bertram, Iain Alexander (Lancaster University, Department of Physics) /ATLAS Collaboration
Measurements of jet substructure variables are presented using data collected in 2016 by the ATLAS experiment at the LHC with proton-proton collisions at $\sqrt{s}$ = 13 TeV. Large-radius jets groomed with the trimming and soft-drop algorithms are studied. [...]

Module Development for the Phase-2 ATLAS ITk Pixel Upgrade / Beck, Helge Christoph (Georg-August-Universitat Goettingen, II. Physikalisches Institut) /ATLAS Collaboration
For the high luminosity era of the Large Hadron Collider (HL-LHC) it is foreseen to replace the current inner tracker of the ATLAS experiment with a new, all-silicon detector to cope with the occurring increase in occupancy, bandwidth and radiation damage. It will consist of an inner pixel and outer strip detector aiming to provide tracking coverage up to |η|=4. [...]

The ATLAS Run-2 Trigger Menu / Russell, Heather Lynn (McGill University, Department of Physics) ; ATLAS Collaboration /ATLAS Collaboration
The ATLAS experiment aims at recording about 1 kHz of physics collisions, starting with an LHC design bunch crossing rate of 40 MHz. To reduce the significant background rate while maintaining a high selection efficiency for rare physics events (such as beyond the Standard Model physics), a two-level trigger system is used. [...]

Searches for direct pair production 
of third generation squarks 
with the ATLAS detector / Yoshihara, Keisuke (Department of Physics and Astronomy, University of Pennsylvania) /ATLAS Collaboration
Naturalness arguments for weak-scale supersymmetry favour supersymmetric partners of the third generation quarks with masses light enough to be produced at the LHC. The ATLAS experiment has a variety of analyses devoted to stop direct production exploiting advanced analysis techniques. [...]

Recently collected data by the ATLAS experiment at the LHC offer opportunities to explore dynamic properties of quark-gluon plasma. A new tool to study these properties is the modified Pearson's correlation coefficient, $\rho$. [...]

Searches for electroweak production of supersymmetric particles involving the Higgs boson and the higgsino with ATLAS / Alonso, Francisco (Universidad National de La Plata (UNLP)) /ATLAS Collaboration
Fine-tuning arguments suggest the mass of the supersymmetric partner of the Higgs boson, the higgsino, is not too far from the weak scale.  The search for higgsinos represents an experimental challenge due to the near mass-degeneracy resulting in soft decay products, and the low production cross section. This talk presents recent ATLAS results of analyses explicitly targeting the higgsino with a variety of experimental techniques, as well as searches for electroweak production of supersymmetric particles in final states involving the Higgs boson..

ATLAS Open Data: Using Education Resources Effectively / Haaland, Even Simonsen (University of Oslo) ; Sanchez Pineda, Arturo Rodolfo (INFN Gruppo Collegato di Udine, Dipartimento Politecnico di Ingegneria ed Architettura, Universita' di Udine, Udine) /ATLAS Collaboration
Perform data analysis and visualisation on your own computer? Yes, you can! Commodity computers are now very powerful in comparison to only a few years ago. On top of that, the performance of today's software and data development techniques facilitates complex computation with fewer resources. [...]
