(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
This paper presents a measurement of the polarisation of τ leptons produced in Z/γ ∗ → τ τ decays which is performed with a dataset of proton—proton collisions at √s = 8 TeV, corresponding to an integrated luminosity of ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
The differential cross-section for the production of a W boson in association with a top quark is measured for several particle-level observables. The measurements are performed using 36.1 fb−1 of pp collision data collected ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
A search for charged Higgs bosons heavier than the top quark and decaying via H± → tb is presented. The data analysed corresponds to 36.1 fb−1 of pp collisions at √ s = 13 TeV and was recorded with the ATLAS detector at ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
A search for electroweak production of supersymmetric particles in scenarios with compressed mass spectra in final states with two low-momentum leptons and missing transverse momentum is presented. This search uses ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses proton-proton collision data corresponding to an integrated luminosity of 36.1 ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
A detailed study of multiparticle azimuthal correlations is presented using pp data at √s = 5.02 and 13 TeV, and p+Pb data at √sNN = 5.02 TeV, recorded with the ATLAS detector at the CERN Large Hadron Collider. The azimuthal ...

The modification of the production of J/ψ, ψ(2S), and Υ (nS) (n = 1, 2, 3) in p+Pb collisions with respect to their production in pp collisions has been studied. The p+Pb and pp datasets used in this paper correspond to ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
This paper presents a direct measurement of the decay width of the top quark using tt ¯ events in the lepton+jets final state. The data sample was collected by the ATLAS detector at the LHC in proton–proton collisions at ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
A search for doubly charged Higgs bosons with pairs of prompt, isolated, highly energetic leptons with the same electric charge is presented. The search uses a proton– proton collision data sample at a centre-of-mass energy ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
A search for weakly interacting massive darkmatter particles produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and missing transverse momentum are considered. ...
