(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
The performance of the ATLAS Inner Detector alignment has been studied using pp collision data at s√=13TeV collected by the ATLAS experiment during Run 2 (2015–2018) of the Large Hadron Collider (LHC). The goal of the ...

This paper presents a search for new heavy particles decaying into a pair of top quarks using 139 fb−1 of proton-proton collision data recorded at a centre-of-mass energy of s√ = 13 TeV with the ATLAS detector at the Large ...

This paper presents a search for direct top squark pair production in events with missing transverse momentum plus either a pair of jets consistent with Standard Model Higgs boson decay into b-quarks or a same-flavour ...

The PreProcessor of the ATLAS Level-1 Calorimeter Trigger prepares the analogue trigger signals sent from the ATLAS calorimeters by digitising, synchronising, and calibrating them to reconstruct transverse energy deposits, ...

A search for Higgs boson decays into a Z boson and a light resonance in two-lepton plus jet events is performed, using a pp collision dataset with an integrated luminosity of 139 fb−1 collected at √s=13 TeV by the ATLAS ...

The production of a prompt photon in association with a Z boson is studied in proton-proton collisions at a centre-of-mass energy s√ = 13 TeV. The analysis uses a data sample with an integrated luminosity of 139 fb−1 ...
