• #### Two particle correlation effects from rotation and instabilities in heavy ion collisions ﻿

(Master thesis, 2013-05-18)
Two particle correlations are studied in the reaction plane of peripheral relativistic heavy ion reactions where the initial state has substantial angular momentum. The earlier predicted rotation effect and Kelvin Helmholtz ...
• #### Two- and three-pion quantum statistics correlations in Pb-Pb collisions at √sNN = 2.76 TeV at the CERN Large Hadron Collider ﻿

(Peer reviewed; Journal article, 2014-02-26)
Correlations induced by quantum statistics are sensitive to the spatiotemporal extent as well as dynamics of particle-emitting sources in heavy-ion collisions. In addition, such correlations can be used to search for the ...

(Peer reviewed; Journal article, 2019-10-10)
We present measurements of two-particle differential number correlation functions R 2 and transverse momentum correlation functions P 2 , obtained from p -Pb collisions at 5.02 TeV and Pb-Pb collisions at 2.76 TeV. The ...
• #### Two-Photon Decay of Non-Standard Higgs Bosons ﻿

(Master thesis, 1999)
• #### Two-photon double ionization of helium by attosecond laser pulses: Evidence of highly correlated electron motion ﻿

(Peer reviewed; Journal article, 2012)
We apply a recently developed ab initio numerical framework to investigate the angular distributions of the emitted electrons in the immediate proximity of the threshold for the two-photon double ionization of helium. ...
• #### Two-pion femtoscopy in p-Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV ﻿

(Peer reviewed; Journal article, 2015-03)
We report the results of the femtoscopic analysis of pairs of identical pions measured in p-Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV. Femtoscopic radii are determined as a function of event multiplicity and ...
• #### Ultrasonic measurement systems with diffraction correction for gas ﻿

(Master thesis, 2017-09-30)
• #### Underlying event properties in pp collisions at √s = 13 TeV ﻿

(Journal article; Peer reviewed, 2020)
This article reports measurements characterizing the Underlying Event (UE) associated with hard scatterings at midrapidity (|η| < 0.8) in pp collisions at √s = 13 TeV. The hard scatterings are identified by the leading ...
• #### Understanding the correlation between (g − 2) μ and μ → eγ in the MSSM ﻿

(Peer reviewed; Journal article, 2014-08)
The supersymmetric contributions to the muon anomalous magnetic moment a μ and to the decay μ → eγ are given by very similar Feynman diagrams. Previous works reported correlations in specific scenarios, in particular if a ...
• #### Universality of Lower Hybrid Waves at Earth's Magnetopause ﻿

(Journal article; Peer reviewed, 2019)
Waves around the lower hybrid frequency are frequently observed at Earth's magnetopause and readily reach very large amplitudes. Determining the properties of lower hybrid waves is crucial because they are thought to ...
• #### Unlocking multimodal PET-MR synergies for geoscience ﻿

(Journal article; Peer reviewed, 2020)
The recent combination of positron emission tomography (PET) and magnetic resonance (MR) imaging modalities in one clinical diagnostic tool represents a scientific advancement with high potential impact in geoscientific ...
• #### Unveiling the strong interaction among hadrons at the LHC ﻿

(Journal article; Peer reviewed, 2020)
One of the key challenges for nuclear physics today is to understand from first principles the effective interaction between hadrons with different quark content. First successes have been achieved using techniques that ...
• #### Update on the CP-Violating Inert-Doublet Model ﻿

(Conference object; Peer reviewed; Journal article, 2012)
We have updated a recently proposed extension of the Inert Doublet Model. The extension amounts to the addition of an extra non-inert scalar doublet. The model thus offers a possibility of CP violation in the scalar sector ...
• #### Upgrade of the ALICE central barrel tracking detectors: ITS and TPC ﻿

(Peer reviewed; Journal article, 2019-02)
The ALICE Collaboration will undertake a major upgrade of the detector apparatus during the second LHC Long Shutdown LS2 (2019–2020) in view of the Runs 3 and 4 (2021–2029). The objective of the upgrade is two-fold: i) an ...
• #### Upscaling on Fracture Flow Models ﻿

(Master thesis, 2017-08-25)
Fractures have a great impact on the quality of a porous media. The understanding of the fractures is important to describe the challenges linked to flow of geothermal heat, the transport of groundwater or transport of ...
• #### Use of market ready light dosimeters for patients with erythropoietic protoporphyria disorder ﻿

(Master thesis, 2017-06-21)
Erythropoietic protoporphyria (EPP) disorder causes severe pain in the skin when patients are overexposed to light, particularly blue light. These patients can only stay exposed to sunlight for a short amount of time, and ...

Solar radiation (200–4,000 nm) is very important for the climate system on Earth. It provides heat and drives the photosynthesis in plants to fuel all life. It plays a major role in the original synthesis of biomolecules ...
• #### Vannbasert eor i oppsprukne bergarter - økt oljeutvinning ved kjemikalietilsetning i injeksjonsvannet ﻿

(Master thesis, 2010-06-01)
En stor del av verdens hydrokarbonreserver finnes i karbonater. Karbonatreservoarer er komplekse fordi reservoarbergarten ofte er sprø og sprekker lett. Mineralsammensetningen av karbonater gjør poreoverflaten mer tilbøyelig ...
