Measurement of prompt photon production and W/Z boson production in association with jets at ATLAS / Torres, Heberth (Technische Universitaet Dresden (DE)) /ATLAS Collaboration
Measurement of prompt photon production and W/Z boson production in association with jets at ATLAS The production of prompt isolated photons and W/Z-boson in association with jets are an important test of perturbative QCD prediction and also yield information about the parton distribution functions of the proton. In this talk, we present the latest measurements of prompt photon production using proton-proton collision data collected by the ATLAS experiment at √s=13 TeV. [...]

Search for rare decays of the Higgs boson with the ATLAS detector / Basalaev, Artem (Deutsches Elektronen-Synchrotron (DE)) /ATLAS Collaboration
The Standard Model predicts several rare Higgs boson decay channels, among which are decays to a $Z$ boson and a photon, $H\rightarrow Z\gamma$, and to a low-mass lepton pair and a photon $H→\ell\ell\gamma$. The observation of these decays could open the possibility of studying the CP and coupling properties of the Higgs boson in a complementary way to other analyses. [...]

Triggering in ATLAS in Run 2 and Run 3 / Okumura, Yasuyuki (University of Tokyo (JP)) /ATLAS Collaboration
The ATLAS experiment at the LHC can record about 1 kHz of physics collisions, out of an LHC design bunch crossing rate of 40 MHz. To achieve a high selection efficiency for rare physics events while reducing the significant background rate, a two-level trigger system is used. [...]

FELIX and the SW ROD / ATLAS TDAQ Collaboration /ATLAS Collaboration
After the current LHC shutdown (2019-2022), the ATLAS experiment will be required to operate in an increasingly harsh collision environment. To maintain physics performance, the ATLAS experiment is undergoing a series of upgrades. [...]

ATLAS LAr Calorimeter Commissioning for LHC Run-3 / Mungo, Davide Pietro (Università degli Studi e INFN Milano (IT)) /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. After detector consolidation during a long shutdown, Run-2 started in 2015 and about 150fb-1 of data at a center-of-mass energy of 13 TeV was recorded [...]

Measurements of diffractive physics and soft QCD at ATLAS / Beresford, Lydia Audrey (CERN) /ATLAS Collaboration
In this talk we present various measurements of diffractive physics and soft QCD processes performed using data collected by the ATLAS experiment at the LHC. Single diffractive processes (pp->pX) are studied reconstructing the particles from the dissociative system (X) with the ATLAS detector, while the intact proton is reconstructed and measured in a forward detector.

Measurements and interpretations of STXS, differential and fiducial cross sections in Higgs boson decays to two photons with the ATLAS detector / Rossi, Eleonora (Centre National de la Recherche Scientifique (FR)) /ATLAS Collaboration
Higgs boson decays to two photons can be selected with high efficiency, and the very good invariant mass resolution allows a robust subtraction of the backgrounds. This talk will present measurements of Simplified Template Cross Sections, differential and fiducial cross sections, as measured in the diphoton decay channel by the ATLAS detector using the full Run 2 dataset of pp collision data collected at 13 TeV at the LHC, and their respective interpretations in the context of an Effective Field Theory..

Measurements of multi-boson production at ATLAS / Metcalfe, Jessica (Argonne National Laboratory (US)) /ATLAS Collaboration
Measurements of multiple electroweak bosons production at the LHC constitute an important test of the Standard Model. They are sensitive to the properties of electroweak-boson self-interactions and provide a test of the electroweak theory and of the perturbative quantum chromodynamics. [...]

Searches for new physics with leptons using the ATLAS detector / Zanzi, Daniele (Albert Ludwigs Universitaet Freiburg (DE)) /ATLAS Collaboration
Many theories beyond the Standard Model predict new phenomena, such as Z’, W’ bosons or heavy neutrinos, in final states with isolated, high-pt leptons (e/mu/tau). Searches for new physics with such signatures, produced either resonantly or non-resonantly, including a general search using multilepton final states are performed using the ATLAS experiment at the LHC.
