(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
This paper presents measurements of tt¯ production in association with additional b-jets in pp collisions at the LHC at a centre-of-mass energy of 13 TeV. The data were recorded with the ATLAS detector and correspond to ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
Inclusive and differential cross-sections for the production of a top-quark pair in association with a photon are measured with proton-proton collision data corresponding to an integrated luminosity of 36.1 fb−1, collected ...

A measurement of the associated production of a top-quark pair (t¯t) with a vector boson (W, Z) in proton-proton collisions at a center-of-mass energy of 13 TeV is presented, using 36.1 fb−1 of integrated luminosity collected ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
The top quark mass is measured using a template method in the tt ¯ → lepton + jets channel (lepton is e or μ) using ATLAS data recorded in 2012 at the LHC. The data were taken at a proton–proton centre-of-mass energy of ...

A search for new particles decaying into a pair of top quarks is performed using proton-proton collision data recorded with the ATLAS detector at the Large Hadron Collider at a center-of-mass energy of √s=13 TeV corresponding ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
This paper describes a search for events with one top-quark and large missing transverse momentum in the final state. Data collected during 2015 and 2016 by the ATLAS experiment from 13 TeV proton–proton collisions at the ...
