(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
This paper presents combinations of inclusive and differential measurements of the charge asymmetry (AC) in top quark pair (t¯t) events with a lepton+jets signature by the ATLAS and CMS Collaborations, using data from LHC ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
The coupling properties of the Higgs boson are studied in the four-lepton (e, µ) decay channel using 36.1 fb−1 of pp collision data from the LHC at a centre-of-mass energy of 13 TeV collected by the ATLAS detector. Cross ...
Search for high-mass resonances decaying to τν in pp collisions at √s=13 TeV with the ATLAS detector
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
A search for high-mass resonances decaying to τν using proton-proton collisions at ffiffi s p ¼ 13 TeV produced by the Large Hadron Collider is presented. Only τ-lepton decays with hadrons in the final state are considered. ...

Measurements are made of differential cross-sections of highly boosted pair-produced top quarks as a function of top-quark and t¯t system kinematic observables using proton-proton collisions at a center-ofmass energy of ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
A search for pair production of up-type vector-like quarks (T) with a significant branching ratio into a top quark and either a Standard Model Higgs boson or a Z boson is presented. The same analysis is also used to search ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
A search for the standard model Higgs boson produced in association with a top-quark pair, t¯tH, is presented. The analysis uses 36.1 fb−1 of pp collision data at ffiffi s p ¼ 13 TeV collected with the ATLAS detector at ...

A search for W -boson production in the W → t¯ b → qq¯ b¯ b decay channel is presented using 36.1 fb−1 of 13 TeV proton–proton collision data collected by the ATLAS detector at the Large Hadron Collider in 2015 and 2016. ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
The production of a top quark in association with a Z boson is investigated. The proton–proton collision data collected by the ATLAS experiment at the LHC in 2015 and 2016 at a centre-of-mass energy of √s = 13 TeV are used, ...
