(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)A search for the associated production of the Higgs boson with a top quark pair (t¯tH) is reported. The search is performed in multilepton final states using a data set corresponding to an integrated luminosity of 36.1 ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)The γ-ray strength function of 56Fe has been measured from proton-γ coincidences for excitation energies up to ≈11 MeV. The low-energy enhancement in the γ-ray strength function, which was first discovered in the (3He,αγ)56Fe ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)A search for the production of three massive vector bosons in proton–proton collisions is performed using data at √s = 13 TeV recorded with the ATLAS detector at the Large Hadron Collider in the years 2015–2017, corresponding ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)A search is presented for four-top-quark production using an integrated luminosity of 139 fb−1 of proton–proton collision data at a centre-of-mass energy of 13 TeV collected by the ATLAS detector at the LHC. Events are ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Recently, several magnetic resonance imaging (MRI) studies have reported time-of-day effects on brain structure and function. Due to the possibility that time-of-day effects reflect mechanisms of circadian regulation, the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract Cortical microstructure is influenced by circadian rhythm and sleep deprivation, yet the precise underpinnings of these effects remain unclear. The ratio between T 1 -weighted and T 2 -weighted magnetic resonance ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)It is known that (ZnO)1−x(GaN)x alloys demonstrate remarkable energy band bowing, making the material absorb in the visible range, in spite of the binary components being classical wide band gap semiconductors. However, ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)There is sparse direct experimental evidence that atomic nuclei can exhibit stable “pear” shapes arising from strong octupole correlations. In order to investigate the nature of octupole collectivity in radium isotopes, ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)The level structure of 158Er has been studied using the Gammasphere spectrometer via the 114Cd(48Ca,4n) reaction at 215 MeV with both thin (self-supporting) and thick (backed) targets. The level scheme has been considerably ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The experimental γ-ray strength functions (γSFs) of 142,144–151Nd have been studied for γ-ray energies up to the neutron separation energy using the Oslo method. The results represent a unique set of γSFs for an isotopic ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Two-particle number and transverse momentum correlations are powerful tools for studying the medium produced in heavy-ion collisions. Correlations in the angular separation of pairs of hadrons can provide information on ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)The dynamics occurring at the terrestrial magnetopause are investigated by using Geotail and THEMIS spacecraft data of magnetopause crossings during ongoing Kelvin–Helmholtz instability. Properties of plasma turbulence and ...
