Long term aging studies of the new PMTs used for the HL-LHC ATLAS hadron calorimeter upgrade / Chiarelli, Giorgio (Universita & INFN Pisa (IT)) ; Leone, Sandra (Universita & INFN Pisa (IT)) ; Scuri, Fabrizio (Universita & INFN Pisa (IT)) /ATLAS Collaboration
The central hadron calorimeter (TileCal) of the ATLAS experiment at the Large Hadron Collider (LHC) is a sampling calorimeter made up of steel plates, as absorbers, and scintillating tiles, as active materials. It is read out by wavelength shifting fibers carrying light to about 10,000 photomultipliers (PMTs). [...]

Overview of the ATLAS High-Granularity Timing Detector: project status and results / Jia, Xuewei (Chinese Academy of Sciences (CN)) /ATLAS Collaboration
The increase of the particle flux (pile-up) at the HL-LHC with instantaneous luminosities up to L ≃ 7.5 × 1034 cm−2s−1 will have a severe impact on the ATLAS detector reconstruction and trigger performance. The end-cap and forward region where the liquid Argon calorimeter has coarser granularity and the inner tracker has poorer momentum resolution will be particularly affected. [...]

Low Gain Avalanche Detectors for the ATLAS High Granularity Timing Detector: laboratory and test beam campaigns / Ma, Kuo (University of Science and Technology of China (CN)) /ATLAS Collaboration
The High Granularity Timing Detector (HGTD) is designed for the mitigation of pile-up effects in the ATLAS forward region and for bunch per bunch luminosity measurements. HGTD, based on Low Gain Avalanche Detector (LGAD) technology and covering the pseudorapidity region between 2.4 and 4.0, will provide high precision timing information to distinguish between collisions occurring close in space but well-separated in time. [...]

The ATLAS experiment Phase-I upgrades for the LHC Run-3 / Luci, Claudio (Sapienza Universita e INFN, Roma I (IT)) /ATLAS Collaboration
With the end of RUN-2, the LHC has delivered only 4% of the collision data expected to be available during its lifetime. The now ongoing data-taking campaign -- RUN-3 -- will more than double the integrated luminosity the LHC accumulated during Runs 1 and 2. [...]

Overview of ATLAS Upgrades projects for HL-LHC / Pontecorvo, Ludovico (CERN) /ATLAS Collaboration
With the restart of the proton-proton collision program in 2022 (Run-3) at the Large Hadron Collider (LHC), the ATLAS detector aims to double the integrated luminosity accumulated during the ten previous years of operation. After this data-taking period the LHC will undergo an ambitious upgrade program to be able to deliver an instantaneous luminosity of 7.5×1034 cm−2 s−1, allowing the collection of more than 3 ab−1 of data at 𝑠√=14 TeV.

Probing the Higgs Potential with $HH\to bb \tau\tau$ / Karkout, Osama (Nikhef National institute for subatomic physics (NL)) /ATLAS Collaboration
Double-Higgs (HH) production in the LHC is one of the main sought-after measurements, as it is a direct probe of the Higgs self-coupling originating from the Higgs potential. I propose a poster presenting the search for HH production in the bottom-quark and tau-lepton pairs decay channel. [...]

Searches for new physics in the Higgs sector with the ATLAS detector. / Otero Y Garzon, Gustavo (Universidad de Buenos Aires (AR)) /ATLAS Collaboration
The discovery of the Higgs boson with a mass of 125 GeV completed the particle content predicted by the Standard Model (SM). Even though this model is well established and consistent with many measurements, it is not capable to solely explain some observations. [...]

Spin correlation and entanglement with the ATLAS experiment / Afik, Yoav (University of Chicago (US)) /ATLAS Collaboration
Entanglement is a striking feature of quantum mechanics~\cite{Einstein:1935rr,Schrodinger1935,Bell:1964kc}, with applications in fields such as metrology, cryptography, quantum information, and quantum computation~\cite{Bennett2000,Nielsen2000,Marciniak2022}. It has been observed in a wide variety of systems, ranging from the microscopic \cite{Aspect1982,Hagley1997,Steffen2006,Pfaff2013} to the macroscopic \cite{Julsgaard2001,Lee2011,Ockeloen2018} scale.
