(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)ALICE measured the nuclear modification factor (RAA) and elliptic flow (v2) of D mesons (D0, D+, D∗+ and D+ s ) in semi-central Pb–Pb collisions at √sNN = 5.02 TeV. The increased amount of data in semi-central Pb–Pb events ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)Background: In the context of the investigation of the quark gluon plasma produced in heavy-ion collisions, hadrons containing heavy (charm or beauty) quarks play a special role for the characterization of the hot and dense ...
-
(Master thesis / Masteroppgave, 2017)In this thesis we explore bound state formation from a QFT perspective, which is particularly interesting for dark matter. We explicitly study bound state formation for a pseudo-scalar mediator.

-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)We introduce DarkBit, an advanced software code for computing dark matter constraints on various extensions to the Standard Model of particle physics, comprising both new native code and interfaces to external packages. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The nature of dark matter remains one of the key science questions. Weakly Interacting Massive Particles (WIMPs) are among the best motivated particle physics candidates, allowing to explain the measured dark matter density ...
-
(Doctoral thesis / Doktoravhandling, 2018)There are strong theoretical arguments in favor of the gravitational acceleration being identical for matter and antimatter, as anything else would violate the weak equivalence principle. The weak equivalence principle is ...
-
(Master thesis / Masteroppgave, 2008)Denne oppgaven dreier seg om bruk av datalogging i fysikkundervisningen i videregående skoler. Oppgaven tar for seg følgende forskningsspørsmål: 1. Hvilke forutsetninger har fysikklærere for å bruke datalogging ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)Absorption of radio waves in the polar ionosphere near the magnetic noon was observed on October 8, 1991, by the 30 MHz imaging riometer at Ny-Alesund, Svalbard (invariant latitude 76.1°). These observations showed that ...

(Doctoral thesis / Doktoravhandling, 2013)Hypoxia in tumors has been found to decrease the effectiveness of cancer treatment; in particular, it can diminish the effect of radiation therapy. Furthermore, hypoxia has been associated with malignant progression and ...
-
(Master thesis / Masteroppgave, 2018)Dynamic contrast enhanced (DCE) MRI is increasingly used for tumor imaging, both for clinical use and research. However, existing DCE-based methods have limitations with regard to standardization and reproducibility, ...
-
(Master thesis / Masteroppgave, 2019)From the Sun to the Earth’s upper atmosphere, particles and energy are trans- ported through several key processes. Many of these we know well, and some we are still learning about. In this thesis we will study one of the ...
-
(Master thesis / Masteroppgave, 2010)Et av de mest spennende og minst kjente områdene innenfor eksperimentell kjernefysikk, er spektroskopi av kjerner som nærmer seg stabilitetsgrensen, som for eksempel for kjerner med høy masse og ladning. GABRIELA er et ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Machine learning techniques based on artificial neural networks have been successfully applied to solve many problems in science. One of the most interesting domains of machine learning, reinforcement learning, has a natural ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)It is known that the behavior of residual Li in ion implanted ZnO depends on the preferential localization of the implants, in particular, forming characteristic Li depleted or Li pile-up regions for Zn or O sublattice ...
