(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
Measurements of K0S and Λ0 production in tt¯ final states have been performed. They are based on a data sample with integrated luminosity of 4.6 fb−1 from proton–proton collisions at a centre-of-mass energy of 7 TeV, ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
To assess the properties of the quark–gluon plasma formed in ultrarelativistic ion collisions, the ATLAS experiment at the LHC measures a correlation between the mean transverse momentum and the flow harmonics. The analysis ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
A search for heavy neutral Higgs bosons is performed using the LHC Run 2 data, corresponding to an integrated luminosity of 139 fb−1 of proton-proton collisions at √s=13 TeV recorded with the ATLAS detector. The search ...

A study of the charge conjugation and parity (CP) properties of the interaction between the Higgs boson and top quarks is presented. Higgs bosons are identified via the diphoton decay channel (H→γγ), and their production ...

This Letter presents a search for the production of new heavy resonances decaying into a Higgs boson and a photon using proton-proton collision data at √s=13 TeV collected by the ATLAS detector at the LHC. The data ...

A search for heavy neutral Higgs bosons produced in association with one or two b-quarks and decaying to b-quark pairs is presented using 27.8 fb−1 of √s=13 TeV proton-proton collision data recorded by the ATLAS detector ...

The performance of the ATLAS muon trigger system is evaluated with proton-proton (pp) and heavy-ion (HI) collision data collected in Run 2 during 2015–2018 at the Large Hadron Collider. It is primarily evaluated using ...

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, ...

The top anti-top quark production cross-section is measured in the lepton+jets channel using proton–proton collision data at a centre-of-mass energy of √s = 13 TeV collected with the ATLAS detector at the LHC. The dataset ...
