(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
Measurements of ZZ production in the lþl−l0þl0− channel in proton–proton collisions at 13 TeV center-of-mass energy at the Large Hadron Collider are presented. The data correspond to 36.1 fb−1 of collisions collected by ...
(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. ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
Measurements of longitudinal flow correlations are presented for charged particles in the pseudorapidity range |η| < 2.4 using 7 µb−1 and 470 µb−1 of Pb+Pb collisions at √sNN = 2.76 and 5.02 TeV, respectively, recorded by ...

The efficiency to identify jets containing b-hadrons (b-jets) is measured using a high purity sample of dileptonic top quark-antiquark pairs (tt¯) selected from the 36.1 fb−1 of data collected by the ATLAS detector in 2015 ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
A search is presented for the direct pair production of the stop, the supersymmetric partner of the top quark, that decays through an R-parity-violating coupling to a final state with two leptons and two jets, at least one ...
(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 the direct production of charginos and neutralinos in final states with at least two hadronically decaying tau leptons is presented. The analysis uses a dataset of pp collisions corresponding to an integrated ...
(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 ...

We describe a multi-step “rotating wall” compression of a mixed cold antiproton–electron non-neutral plasma in a 4.46 T Penning–Malmberg trap developed in the context of the AEḡIS experiment at CERN. Such traps are routinely ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
A search for new phenomena in final states containing an e+e− or μ+μ− pair, jets, and large missing transverse momentum is presented. This analysis makes use of proton–proton collision data with an integrated luminosity ...
