11. The Beauty in Broken Symmetries : b-jet identification and searches for Supersymmetry, Dark Matter and multi-Higgs boson production with the ATLAS experiment
Abstract : The Large Hadron Collider is the largest and most powerful accelerator in the world. Proton bunches are accelerated to 6.5 TeV inside the LHC ring in opposite directions and are then collided at four different points around the ring with an energy of 13 TeV. READ MORE

12. Phenomenology in multi-scalar extensions of the Standard Model
Abstract : This thesis is composed of four papers, which all treat various extensions to the Standard Model (SM). The first two papers concern a particular supersymmetric, grand-unified theory (GUT), while in the latter two, we classify anomaly-free implementations of two-Higgs doublet models (2HDM) with a gauged abelian symmetry. Paper I. READ MORE

13. Exploring particle physics beyond the Standard Model
Abstract : The standard model of particle physics (SM) is arguably the best tested theory of physics, providing an accurate description of virtually all high energy particle physics phenomena observable in the laboratory. However, the SM also has a number of shortcomings: some of more theoretical nature such as the fine-tuning problem of the Higgs or the strong-CP problem, and some of more phenomenological nature such as not allowing for a satisfying implementation of neutrino masses and the lack of a suitable candidate for the observed dark matter of the Universe.

14. Search for beyond Standard Model physics with same-sign dileptons
Abstract : An introduction into the theory and experimental background of particle physics and the ATLAS detector is given. The transition radiation tracker (TRT) which is vital to the particle tracking and identification is then described giving particular creedence to the calibration. The automation of this calibration is explained. READ MORE

15. Structures of Polyelectrolyte Multilayers and Preasorbed Mucin : The Influence of Counterions
Abstract : The focus in this thesis has been to gain a fundamental understanding of how different type of salts affect preadsorbed polyelectrolytes, both natural and synthetic. The knowledge from the fundamental work is then applied on a commercial system to investigate if the efficiency can be enhanced. READ MORE
