(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 ...

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 ...

This paper presents a measurement of the W boson production cross section and the W+/W− cross-section ratio, both in association with jets, in proton-proton collisions at √ s = 8 TeV with the ATLAS experiment at the Large ...

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, ...

A measurement of the production of three isolated photons in proton–proton collisions at a centre-of-mass energy √s=8 TeV is reported. The results are based on an integrated luminosity of 20.2 fb−1 collected with the ATLAS ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
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 is conducted for a beyond-the-Standard-Model boson using events where a Higgs boson with mass 125 GeV decays to four leptons (` = e or µ). This decay is presumed to occur via an intermediate state which contains ...
