• #### A trigger readout system for the Forward Calorimeter(FoCal) ﻿

(The University of Bergen, 2012-11-20)
The University of Bergen, Norway is currently involved in the development and building of the Forward Calorimeter (FoCal) as an upgrade to the ALICE (A Large Ion Collider Experiment) detector at CERN (European Organization ...

• #### The true fluence distribution of terrestrial gamma flashes at satellite altitude ﻿

(American Geophysical Union, 2012-03-24)
Peer reviewedJournal article
• #### Turbulence, Vorticity and Lambda Polarization ﻿

(IOP Publishing, 2014)
Present highest energy heavy ion experiments show the dominance of the fluid dynamical processes. The possibility of new collective phenomena, rotation and turbulence occurs, which were known only in macroscopic systems ...

• #### Two Higgs Doublets plus One Dark Matter Singlet ﻿

(The University of Bergen, 2010-08-01)
In this thesis an extension of the 2HDM (see chapter 1) is explored. The extension admits an extra inert singlet which is a dark matter candidate. Before the exploration a large part of the thesis (chapter 2) is an ...
Master thesis
• #### Two mechanisms of stratospheric ozone loss in the Northern Hemisphere, studied using data assimilation of Odin/SMR atmospheric observations ﻿

(Copernicus Publications, 2017-02-07)
Observations from the Odin/Sub-Millimetre Radiometer (SMR) instrument have been assimilated into the DIAMOND model (Dynamic Isentropic Assimilation Model for OdiN Data), in order to estimate the chemical ozone (O3) loss ...
Journal article
• #### Two particle correlation effects from rotation and instabilities in heavy ion collisions ﻿

(The University of Bergen, 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 ...
Master thesis
• #### Two- and three-pion quantum statistics correlations in Pb-Pb collisions at √sNN = 2.76 TeV at the CERN Large Hadron Collider ﻿

(American Physical Society, 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 ...

• #### Two-Photon Decay of Non-Standard Higgs Bosons ﻿

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

(American Physical Society, 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. Provided ...

• #### Two-pion femtoscopy in p-Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV ﻿

(American Physical Society, 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 pair ...

• #### Understanding the correlation between (g − 2) μ and μ → eγ in the MSSM ﻿

(Springer, 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 ...
Journal article
• #### Update on the CP-Violating Inert-Doublet Model ﻿

(The XXth International Workshop High Energy Physics and Quantum Field Theory, 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 ...

• #### Upscaling on Fracture Flow Models ﻿

(The University of Bergen, 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 ...
Master thesis
• #### Use of market ready light dosimeters for patients with erythropoietic protoporphyria disorder ﻿

(The University of Bergen, 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 ...
Master thesis
• #### Using Multivariate Data Analysis and ATR-FTIR Spectroscopy for Modeling Components Present During CO2 Capture with Amines ﻿

(The University of Bergen, 2018-06-20)
This master thesis is a collaboration between Technology Centre Mongstad (TCM) and University of Bergen. The project is to develop a method to accurately predict total inorganic carbon, total alkalinity and density using ...
Master thesis
• #### UV and aerosol climatology based on simulations and measurements by satellites and ground station ﻿

(The University of Bergen, 2013-03-22)
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 ﻿

(The University of Bergen, 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 ...

• #### Vanninjektivitet og svekking av kalk under injeksjon av kaldt vann ﻿

(The University of Bergen, 2014-12-05)
Primær oljeutvinning ved trykkavlastning gir ofte lav utvinningsgrad, og etterlater stor restoljemetning i reservoaret. For å forbedre oljeutvinningsgraden kan andre produksjonsmetoder benyttes; vanninjeksjon har i lang ...
