Development of the ATLAS Liquid Argon Calorimeter Readout Electronics for the HL-LHC / Hulsken, Raphael Alain (McGill University, (CA))
A new era of hadron collisions will begin around 2030 with the High-Luminosity Large Hadron Collider (HL-LHC), which will enable the collection of up to ten times more data than was recorded during the first decade of LHC operations. [...]

The Phase-II Upgrade Projects of ATLAS Tile Calorimeter for the High-Luminosity Era / Chiarelli, Giorgio (Universita & INFN Pisa (IT))
In preparation for the High-Luminosity phase of the LHC, expected to begin in 2030 and delivering a factor of 5 to 7.5 larger the nominal instantaneous luminosity, a comprehensive upgrade of the Tile Calorimeter is underway. [...]

Measurements and identification strategies for non-collision backgrounds in ATLAS experiment / Lahbabi, Fatima Zahra (Universite Hassan II, Ain Chock (MA))
During nominal LHC collisions, protons can interact with residual gas in the beam pipe or with upstream collimators, producing showers of background particles known as Beam-Induced Backgrounds (BIB). [...]

ATLAS New Small Wheel Trigger and Reconstruction Performance Studies with LHC Run-3 data / Orlandini, Romano (Universita e INFN Roma Tre (IT))
The most important ATLAS upgrade for LHC run-3 has been in the Muon Spectrometer, where the replacement of the two forward inner stations with the New Small Wheels (NSW) introduced two novel detector technologies: the small-strip Thin Gap Chambers (sTGC) and the resistive strips Micromegas (MM).

Entanglement effects at high energies (including top quark pair production at threshold) at ATLAS and CMS / Diez Pardos, Carmen (Universitaet Siegen (DE))
The large dataset collected by the ATLAS and CMS detectors at the LHC at the centre-of-mass energy of 13 TeV enables precision testing of theoretical predictions using an extensive sample of top quark events. [...]
