CP Violation in the Two Higgs Doublet Model
(Master thesis, 2010-06)We look into CP violating properties in the two Higgs Doublet Model and search for the possibility that Spontaneous and Explicit CP Violation have no physical difference. -
Experimental and theoretical study on the effect of wall roughness on the phenomenon end of the vortex in swirl tubes
(Master thesis, 2011-11-18)In this thesis, a combination of experimental measurements and numerical simulations are used to investigate the phenomenon "End of the Vortex" in swirl tubes. The main focus here has been comparing swirl tubes containing ... -
An Experimental Investigation of the Influence of Mechanical Damage, Rust and Dust on the Ability of Flame Gaps to Prevent Gas Explosion Transmission
(Master thesis, 2010-11-19)Potential ignition sources, such as motors, light switchers and relays that are located in an industrial area where an explosive atmosphere is a threat, must be designed in such a way that the ignition source does not ... -
Free-standing, axially-symmetric diffraction gratings for neutral matter-waves: experiments and fabrication
(Doctoral thesis, 2011-10-04)Since de Broglie’s famous postulation of the wave-nature of material particles and its subsequent experimental verification, it is known that atoms and molecules behave like waves on a small scale. The investigation of ... -
Gamma-ray flow imaging

A Golden-Channel Higgs Decay
(Master thesis, 2011-06-01)With a Higgs mass greater than 190 GeV and lower than 300 GeV, the decay channel H --> ZZ --> 4l becomes what is referred to as the golden channel for Higgs decay (clean signal). Suppose a pair of on shell Zs with an ... -
Laser excited Li Rydberg atoms in electric and magnetic fields

Limits on the production of the standard model Higgs boson in pp collisions at s=7 TeV with the ATLAS detector
(Peer reviewed; Journal article, 2011-09-20)A search for the Standard Model Higgs boson at the Large Hadron Collider (LHC) running at a centre-of-mass energy of 7 TeV is reported, based on a total integrated luminosity of up to 40 pb−1 collected by the ATLAS detector ... -
Long-range interactions and dynamics of excited atoms
(Master thesis, 2010-06-10)A study of the dynamics of excited hydrogenic atoms, with emphasis on analytical and numerical calculations of the time-independent and the time-dependent Schrõdinger equation. A short description of Rydberg atoms and their ... -
Low-energy surface vibration measurements on the alpha-quartz (0001) surface
(Master thesis, 2011)Despite the enormous range of usages, only little is known about the dynamic and structural properties of quartz (SiO2) surfaces on the atomic scale. The main reason for this is probably that quartz is an insulator, with ... -
Luminosity determination in pp collisions at s=7 TeV using the ATLAS detector at the LHC
(Peer reviewed; Journal article, 2011-04-27)Measurements of luminosity obtained using the ATLAS detector during early running of the Large Hadron Collider (LHC) at s=7 TeV are presented. The luminosity is independently determined using several detectors and multiple ... -
Measurement of dijet production with a veto on additional central jet activity in pp collisions at ps = 7TeV using the ATLAS detector
(Peer reviewed; Journal article, 2011-09-12)A measurement of jet activity in the rapidity interval bounded by a dijet system is presented. Events are vetoed if a jet with transverse momentum greater than 20GeV is found between the two boundary jets. The fraction of ... -
Measurement of inclusive jet and dijet cross sections in proton-proton collisions at 7 TeV centre-of-mass energy with the ATLAS detector
(Peer reviewed; Journal article, 2011-02-03)Jet cross sections have been measured for the first time in proton-proton collisions at a centre-of-mass energy of 7 TeV using the ATLAS detector. The measurement uses an integrated luminosity of 17 nb−1 recorded at the ... -
Measurement of W and Z production in proton-proton collisions at p s = 7 TeV with the ATLAS detector
(Peer reviewed; Journal article, 2011-09-14)We present studies of W and Z bosons with associated high energy photons produced in pp collisions at s=7 TeV. The analysis uses 35 pb−1 of data collected by the ATLAS experiment in 2010. The event selection requires W and ... -
Measurements of underlying-event properties using neutral and charged particles in pp collisions at √ s = 900 GeV and √ s = 7 TeV with the ATLAS detector at the LHC
(Peer reviewed; Journal article, 2011-05-10)We present first measurements of charged and neutral particle-flow correlations in pp collisions using the ATLAS calorimeters. Data were collected in 2009 and 2010 at centre-of-mass energies of 900 GeV and 7 TeV. Events ... -

Molecular Dynamics Study of Selective Adsorption of PCB on Activated Carbon
(Journal article, 2011)The selectivity of PCB adsorption from fish oil onto activated carbon (AC) was investigated by means of molecular dynamics to determine the importance of molecular planarity. PCB congeners 77 and 118 were selected for ... -
Molekylærdynamiske studier av vann- adsorpsjon på hematitt
(Master thesis, 2010-06)I denne oppgaven ser en på hva som skjer på overflaten av en hematittstruktur som blir utsatt for vann. Hematitt er en av strukturene mellom jern og oksygen som i dagliglivet omtales som rust. Sammenlignet med andre ... -
