Ultra-peripheral physics with ATLAS / Gilbert, Benjamin Jacob (Columbia University (US)) /ATLAS Collaboration
This talk gives an overview of the latest ultra-peripheral physics measurements performed with the ATLAS detector at the LHC. These include differential measurements of the exclusive di-muon production cross-section, which are crucial for setting constraints on the initial photon spectrum for all UPC measurements at the LHC; measurements of light-by-light scattering, which result in an observation of this elusive Standard Model process and set competitive limits on the parameter space for axion-like particles; measurements of electromagnetic di-muon production in non-UPC Pb+Pb collisions, which are sensitive to the structure of the initial EM fields and possibly EM content of the created Quark-Gluon Plasma; and measurements of collective behavior in high-multiplicity photo-nuclear collisions..

Commissioning of the BIS78 pilot project of the phase-1 upgrade of the ATLAS muon spectrometer / Tsai, Meng-Ju (University of Michigan (US)) /ATLAS Collaboration
The Monitored Drift Tube (MDT) provides precise tracking and momentum measurement in the ATLAS muon spectrometer. To accommodate higher event rates and provide better fake rejection in the High Luminosity LHC, a new integrated chamber with small-diameter MDT (sMDT) and thin Resistive Plate Chambers (tRPC) had been developed and will be installed into barrel inner layer of the muon detector for the phase-2 upgrade.

Operational Experience and Performance with the ATLAS Pixel detector at the Large Hadron Collider at CERN / Kirchhoff, Andreas (Georg August Universitaet Goettingen (DE)) /ATLAS Collaboration
The tracking performance of the ATLAS detector relies critically on its 4-layer Pixel Detector. The key status and performance metrics of the ATLAS Pixel Detector are summarised, and the operational experience and requirements to ensure optimum data quality and data taking efficiency will be described, with special emphasis to radiation damage experience.

ATLAS results on $J/ψp$ resonances in the $Λ_b→J/ψpK$ decays / Yeletskikh, Ivan (Joint Inst. for Nuclear Research (RU)) ; ATLAS Collaboration /ATLAS Collaboration
A study of J/psi p resonances in the Lambda_b -> J/psi p K decays with large m(pK) invariant masses is presented by the ATLAS experiment at the LHC. The analysis is based on a combined sample of pp collision data at centre-of-mass energies of 7 TeV and 8 TeV corresponding to integrated luminosities of 4.9 fb-1 and 20.6 fb-1, respectively. [...]

Beyond the SM Higgs physics at LHC (Direct and indirect from Higgs couplings) / Dai, Tiesheng (University of Michigan (US)) /ATLAS Collaboration
The discovery of the Higgs boson with the mass of 125 GeV completed the particle content predicted by the Standard Model. Even though this model is well established and consistent with many measurements, it is not capable to solely explain some observations. [...]

ATLAS measurements of CP violation and rare decays processes with beauty mesons / Novotny, Lukas (Czech Technical University in Prague (CZ)) /ATLAS Collaboration
The ATLAS experiment has performed measurements of B- meson rare decays proceeding via suppressed electroweak flavour changing neutral currents, and of mixing and $CP$ violation in the neutral Bs meson system. This talk will focus on the latest results from the ATLAS collaboration, such as rare processes $B^0_s \to \mu \mu$ and $B^0 \to \mu \mu$, and $CP$ violation in the $B_s^0 —> J/\psi \phi$ decays.

Jet flavour tagging for the ATLAS Experiment / Centonze, Martino Salomone (INFN Lecce e Universita del Salento (IT)) /ATLAS Collaboration
The ability to identify jets stemming from the hadronisation of b- quarks (b-jets) is crucial for the physics program of ATLAS. The higher pileup conditions and the growing interest for measurements including c-jets and for searches in the high transverse momentum regime make the task more and more complex. [...]

The high voltage (HV) system of TileCal, the ATLAS central hadron calorimeter, is being upgraded for the HL-LHC, in the so called Phase II Upgrade. In the new configuration for the upgrade, the HV regulation boards are not located inside the detector anymore, they are deployed far from the radiation in a room where there is permanent access for maintenance.
