This report presents a comprehensive collection of searches for new physics performed by
the ATLAS Collaboration during the Run 2 period of data taking at the Large Hadron …

This paper reviews and extends searches for the direct pair production of the scalar
supersymmetric partners of the top and bottom quarks in proton--proton collisions collected …

The luminosity determination for the ATLAS detector at the LHC during Run 2 is presented,
with $ pp $ collisions at $\sqrt {s}= 13$ TeV. The absolute luminosity scale is determined …

The flavour-tagging algorithms developed by the ATLAS Collaboration and used to analyse
its dataset of\(\sqrt {s}= 13\) TeV pp collisions from Run 2 of the Large Hadron Collider are …

This article documents the muon reconstruction and identification efficiency obtained by the
ATLAS experiment for 139 fb^-1 fb-1 of pp collision data at s= 13 s= 13 TeV collected …

Jet energy scale and resolution measurements with their associated uncertainties are
reported for jets using 36–81 fb-1 of proton–proton collision data with a centre-of-mass …

A bstract Measurements of Higgs boson production cross-sections are carried out in the
diphoton decay channel using 139 fb− 1 of pp collision data at\(\sqrt {s}\)= 13 TeV collected …

The ATLAS experiment has developed extensive software and distributed computing
systems for Run 3 of the LHC. These systems are described in detail, including software …

Searches are performed for nonresonant and resonant di-Higgs boson production in the bb¯
γ γ final state. The dataset used corresponds to an integrated luminosity of 139 fb-1 of proton …

The identification of $ b $-jets, referred to as $ b $-tagging, is an important part of many
physics analyses in the ATLAS experiment at the Large Hadron Collider and an accurate …
