11. Searches for New Physics in Single Photon Events and a Search for Charginos at the DELPHI Experiment
Sammanfattning : A search for new physics using events with a single photon and missing energy has been made at the DELPHI experiment together with a search for charginos. The results were based on data collected up to and including the final year of 2000. LÄS MER
12. Bipolär sjukdom - ur ett existentiellt perspektiv
Sammanfattning : Aim: The overall aim was to create knowledge about what it means to live with bipolar disorder from an existential perspective, both for individuals with the diagnosis and for their close relatives.Method: An existential perspective in this context entails that it is explored and described from a lifeworld perspective of individuals who in various ways experience that which is termed as bipolar disorder.

13. The BIG ghost
Sammanfattning : In this thesis we present work done in an analysis of models of brane induced gravity. These are higher dimensional generalizations of Einstein's General relativity where our universe is considered as a brane in a higher dimensional bulk and where the gravitational dynamics on the brane is enhanced.

14. Light from Dark Matter : Hidden Dimensions, Supersymmetry, and Inert Higgs
Sammanfattning : Recent observational achievements within cosmology and astrophysics have lead to a concordance model in which the energy content in our Universe is dominated by presumably fundamentally new and exotic ingredients – dark energy and dark matter. To reveal the nature of these ingredients is one of the greatest challenges in physics. LÄS MER
15. Phenomenological studies of dimensional deconstruction
Sammanfattning : In this thesis, two applications of dimensional deconstruction are studied. The first application is a model for neutrino oscillations in the presence of a large decon- structed extra dimension. In the second application, Kaluza{Klein dark matter from a latticized universal extra dimension is studied. The goal of these projects have been twofold. LÄS MER
