(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)An observation of electroweak W ± Z production in association with two jets in proton–proton collisions is presented. The data collected by the ATLAS detector at the Large Hadron Collider in 2015 and 2016 at a centre-of-mass ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)A search for the decay of the Standard Model Higgs boson into a b¯ b pair when produced in association with a W or Z boson is performed with the ATLAS detector. The data, corresponding to an integrated luminosity of 79.8 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The observation of Higgs boson production in association with a top quark pair (tt H¯ ), based on the analysis of proton–proton collision data at a centre-of-mass energy of 13 TeV recorded with the ATLAS detector at the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)The orbital M1 scissors resonance has been measured for the first time in the quasicontinuum of actinides. Particle-γ coincidences are recorded with deuteron and 3He-induced reactions on 232Th. The residual nuclei 231,232,233Th ...

Observation of light-by-light scattering in ultraperipheral Pb+Pb collisions with the ATLAS detector (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)There is a large body of evidence that atomic nuclei can undergo octupole distortion and assume the shape of a pear. This phenomenon is important for measurements of electric-dipole moments of atoms, which would indicate ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Throat auroras have been suggested to be related to indentations on the subsolar magnetopause. However, the indentation generation process and the resulting ionospheric responses have remained unknown. An EISCAT Svalbard ...
-
(Master thesis / Masteroppgave, 2009)This thesis discusses substructures within convecting large-scale plasma density enhancements, known as “patches”, in the polar F-region ionosphere. Two days of high resolution EISCAT Svalbard Radar (ESR) data from both ...

Olivine Grain Size Distributions in Faults and Shear Zones: Evidence for Nonsteady State Deformation (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The grain size distribution of deformed rocks may provide valuable information about their deformation history and the associated mechanisms. Here we present a unique set of olivine grain size distributions from ultramafic ...
-
(Master thesis / Masteroppgave, 2007)The introduction of turbo codes in 1993 was a breakthrough in constructing error correction codes that were able to approach the theoretical limit of performance. Different implementations of turbo codes have become widely ...

On separate chemical freeze-outs of hadrons and light (anti)nuclei in high energy nuclear collisions (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)The climatology map of the GPS phase scintillation identifies two regions of high scintillation occurrences: around magnetic noon and around magnetic midnight. The scintillation occurrence rate is higher around noon, while ...
-
(Master thesis / Masteroppgave, 2020)In this thesis the effect of Autler-Townes splitting is revisited and the dynamics of a 2- and 3-level quantum systems, exhibiting this effect, is studied. This effect is a special case of the Stark effect, where the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The influence of sulfur contamination on the corrosion-fatigue behavior of a polycrystalline superalloy used in aero-engines is considered. Samples tested under a variety of environmental conditions (including exposures ...
