• #### Proton computed tomography readout testing and detector design ﻿

(Master thesis, 2017-10-11)
Proton computed tomography is a way of using protons instead of x-rays to make a three dimensional image of a scanned object. This will result in more accurate predictions for proton treatments and less radiation in the ...

(Peer reviewed; Journal article, 2016-02)
The pseudorapidity $\eta$ and transverse-momentum $p_{\rm T}$ distributions of charged particles produced in proton-proton collisions are measured at the centre-of-mass energy $\sqrt{s}$ = 13 TeV. The pseudorapidity ...

(Peer reviewed; Journal article, 2013-01)
The charged-particle pseudorapidity density measured over 4 units of pseudorapidity in non-single-diffractive (NSD) p-Pb collisions at a centre-of-mass energy per nucleon pair $\sqrt{s_{NN}}$ = 5.02 TeV is presented. The ...
• #### Pseudorapidity dependence of the anisotropic flow of charged particles in Pb-Pb collisions at $\sqrt{s_{\rm NN}}=2.76$ TeV ﻿

(Peer reviewed; Journal article, 2016-11)
We present measurements of the elliptic $\mathrm{v}_2$ , triangular $\mathrm{v}_3$ and quadrangular $\mathrm{v}_4$ anisotropic azimuthal flow over a wide range of pseudorapidities $-3.5< \eta < 5$ . The ...
• #### PVCap as kinetic hydrate inhibitor in gas-water system ﻿

(Master thesis, 2009-11-20)
In this work, molecular dynamic (MD) simulations were employed on different model systems of practical and theoretical significance to investigate possible mechanisms of kinetic hydrate inhibition. Water/methane interface ...
• #### p−p, p−Λ, and Λ−Λ correlations studied via femtoscopy in pp reactions at √s=7 TeV ﻿

(Peer reviewed; Journal article, 2019-02)
We report on the first femtoscopic measurement of baryon pairs, such as p − p , p − Λ , and Λ − Λ , measured by ALICE at the Large Hadron Collider (LHC) in proton-proton collisions at √ s = 7 TeV . This study demonstrates ...
• #### Quantitative Pore-Scale Analysis of CO2 Foam for CCUS ﻿

(Master thesis, 2019-12)
This experimental thesis is a part of ongoing projects lead by the Reservoir Physics group at the Department of Physics and Technology, University of Bergen. The main objectives of this thesis were to develop image analysis ...
• #### Quantum control and characterization of ultrafast ionization with orthogonal two-color laser pulses ﻿

(Peer reviewed; Journal article, 2020-01-14)
We study ultrafast ionization dynamics using orthogonally polarized two-color (OTC) laser pulses involving the resonant “first plus second” (ω + 2ω) scheme. The scheme is illustrated by numerical simulations of the ...
• #### Quarkonium measurements in nucleus–nucleus collisions with ALICE ﻿

(Peer reviewed; Journal article, 2019)
Quarkonia, i.e. bound states of bb¯ and cc¯ quarks, are powerful observables to study the properties of nuclear matter under extreme conditions. The formation of a Quark-Gluon Plasma (QGP), which is predicted by lattice ...
• #### Quarkonium production in p-Pb collisions with ALICE ﻿

(Peer reviewed; Journal article, 2019)
ALICE has measured quarkonium production in p-Pb collisions at backward (−4.46 < ycms < −2.96), mid (−1.37 < ycms < 0.43) and forward (2.03 < ycms < 3.53) rapidity (y) regions down to zero transverse momentum (pT). The ...
• #### Quarkyonic matter from hydro and rapid freeze out ﻿

(Peer reviewed; Journal article, 2009)
Quarkyonic matter is a predicted phase between deconfined ideal QGP and Hadronic matter where the dominant degrees of freedom are quarks. Collective flow measurements indicate that the flow developed in QGP, as flow ...
• #### R-parity violating chargino decays at the LHC ﻿

(Peer reviewed; Journal article, 2014-12)
Supersymmetric models with R-parity violation (RPV) have become more popular following the lack of any excess of missing energy events at the 8 TeV LHC. To identify such models, the suggested searches generally rely on the ...
• #### Radiation treatment monitoring using multimodal functional imaging: PET/CT (18F-Fluoromisonidazole & 18F-Fluorocholine) and DCE-US ﻿

(Peer reviewed; Journal article, 2015-12-18)
Background: This study aims to assess the effect of radiation treatment on the tumour vasculature and its downstream effects on hypoxia and choline metabolism using a multimodal approach in the murine prostate tumour model ...

(Peer reviewed; Journal article, 2015-06)
We have studied the transverse-momentum $p_{\rm T}$ dependence of the inclusive J/\).psi\) production in p-Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV, in three center-of-mass rapidity $y_{\rm cms}$ regions, ...
• #### Reaching towards higher masses of supersymmetric particles decaying to tau leptons ﻿

(Master thesis, 2014-06-30)
This thesis presents an optimisation of the search for SUSY in final states with one tau lepton, jets and missing transverse energy. The SUSY model considered is mSUGRA with the parameter values: A_0 = -2m0, tan(beta) = ...
• #### Reactive transport modelling of hydrate phase transition dynamics in porous media ﻿

(Doctoral thesis, 2015-03-27)
Gas hydrate is believed to be so abundant in nature that some estimates suggest it contains more than two times equivalent energy of the whole fossil fuels on Earth. Besides, reservoir hydrates have other important aspects ...
• #### Reactive Transport of CO2 in Saline Aquifers with implicit geomechanical analysis ﻿

(Peer reviewed; Journal article, 2009)
Geological storage of CO2 in saline aquifers is a promising way to reduce the concentration of the greenhouse gas in the atmosphere. Injection of CO2 will, however, lead to dissolution of minerals in regions of lowered pH ...
