Search for associated production of a Z boson with an invisibly decaying Higgs boson or dark matter candidates with the ATLAS detector using full Run-II Data at LHC / Arena, Eloisa (University of Liverpool (GB)) /ATLAS Collaboration
In the Standard Model, the Higgs boson can decay invisibly only through two Z bosons further decaying to neutrinos. The branching ratio for this process is predicted to be very small. [...]

"Search for light long-lived neutral particles that decay to collimated pairs of leptons or light hadrons with the ATLAS detector and the full Run-II Data at LHC" / Biondini, Alessandro (University of Liverpool (GB)) /ATLAS Collaboration
Several possible extensions to the Standard Model (SM) predict the existence of a dark sector that is weakly coupled to the visible one. A widely studied case is one in which the two sectors couple via the vector portal, where a dark photon with a non-negligible lifetime and a mass in the MeV to GeV range mixes kinetically with the SM photon.

Electroweak physics - experimental overview / Kepka, Oldrich (Czech Academy of Sciences (CZ)) /ATLAS Collaboration
In the talk, we review recent measurements from ATLAS, D0, CMS and LHCb regarding the electroweak physics. The extraction of weak mixing angle and the mass of the W boson, as well as the measurements of the branching fractions of massive electroweak bosons is discussed. [...]

Performance of boosted boson/top taggers, including applications in physics analyses in ATLAS / Liu, Yanlin (University of Michigan (US)) /ATLAS Collaboration
Many new-physics signatures at the LHC produce highly boosted particles, leading to close-by objects in the detector and necessitating jet substructure techniques to disentangle the hadronic decay products. This talk will focus on the tagging methods recently developed within the ATLAS collaboration to identify boosted top-quarks, vector- and Higgs-bosons. [...]

Measurement of Z boson production in association with jets at ATLAS / Laurier, Alexandre (Carleton University (CA)) /ATLAS Collaboration
Measurements of W/Z-boson production in association with jets are an important test of perturbative QCD prediction and also yield information about the parton distribution functions of the proton. Cross sections for Z-boson production in association with jets of high transverse momentum are presented. [...]

Electron and photon energy measurement calibration with the ATLAS detector / Lucio Alves, Fabio Lucio (Nanjing University (CN)) /ATLAS Collaboration
The energy calibration of electron and photons is an important ingredient for many physics analysis, in particular, the precise measurements. In this poster, the overview on the calibration scheme procedure and the some of the measurements as well as the systematic uncertainties estimated are shown..

The measurement for a Standard Model Higgs boson, produced in association with a W or Z boson, decaying into a pair of b-quarks in pp collisions at 13 TeV with the ATLAS detector / Tee, Amy (University of Wisconsin Madison (US)) /ATLAS Collaboration
Following the discovery of the Higg's boson in 2012 by both the ATLAS and CMS experiments, a wealth of papers have been published concerning measurements or observations of the Higgs' decay modes. However, the most dominant decay mode, $H→b\bar{b}$, proved to be an elusive and challenging search due to the low signal-to-background environment, and a diverse range of backgrounds arising from multiple Standard Model processes.

Combined ATLAS Higgs boson measurements and EFT/new-physics interpretations / Mildner, Hannes (University of Sheffield (GB)) /ATLAS Collaboration
Combining measurements of many production and decay channels of the observed Higgs boson allows for the highest possible measurement precision for the properties of the Higgs boson and its interactions. These combined measurements are interpreted in various ways; specific scenarios of physics beyond the Standard Model are tested, as well as a generic extension in the framework of the Standard Model Effective Field Theory.
