(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)
Inclusive J/ψ production is studied in p–Pb interactions at a centre-of-mass energy per nucleon-nucleon collision √ sNN = 8.16 TeV, using the ALICE detector at the CERN LHC. The J/ψ meson is reconstructed, via its decay ...

A search for neutral heavy resonances is performed in the W W → eνμν decay channel using pp collision data corresponding to an integrated luminosity of 36.1 fb−1, collected at a centre-of-mass energy of 13 TeV by the ATLAS ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
A search for an invisibly decaying Higgs boson or dark matter candidates produced in association with a leptonically decaying Z boson in proton–proton collisions at √s = 13 TeV is presented. This search uses 36.1 fb−1 of ...

A search for long-lived, massive particles predicted by many theories beyond the Standard Model is presented. The search targets final states with large missing transverse momentum and at least one highmass displaced vertex ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
A search is presented for photonic signatures, motivated by generalized models of gauge-mediated supersymmetry breaking. This search makes use of proton-proton collision data at ffiffi s p ¼ 13 TeV corresponding to an ...
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. ...
