• #### Limits on the production of the standard model Higgs boson in pp collisions at s=7 TeV with the ATLAS detector ﻿

(Springer, 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 lived charginos in Natural SUSY? ﻿

(Springer, 2014-05-05)
Supersymmetric models with a small chargino-neutralino mass difference, and as a result metastable charginos, have been a popular topic of investigation in collider phenomenology. The possibility of a chargino lighter ...

• #### Low Salinity Waterflood in Combination with Surfactant/Polymer: Effect of Brine Composition ﻿

(The University of Bergen, 2014-06-02)
The effect of low salinity water (LSW) on enhanced oil recovery has been known for decades. Although much research is done on the topic, a general agreement of the prevailing mechanism for the low salinity effect has still ...
Master thesis
• #### Low Salinity Waterflood in Combination with Surfactant/Polymer; Effect of Surfactant Slug Size ﻿

(The University of Bergen, 2014-06-02)
In last years, there has been a growing interest in the effect of reducing salinity of injected water in oil recovery. Many studies have showed that low salinity waterflooding is a promising method that can lead to a ...

• #### Low-energy surface vibration measurements on the alpha-quartz (0001) surface ﻿

(The University of Bergen, 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 ...
