6. Fundamental properties of neutrinos: masses and mixings
Sammanfattning : Neutrino physics is one of the fastest growing topic in phenomenological high energy physics. Neutrinos are elementary neutral particles and participate only in the weak interactions. For this reason it is very difficult to detect them experimentally. Nevertheless, much experimental progress has been obtained in the recent years. LÄS MER
7. Preparations for the next solar WIMP Analysis with IceCube : Advances in simulation, filtering, event topology identification and analysis approach
Sammanfattning : In the year 2011 the construction of IceCube, a neutrino observatory buried in deep clear Antarctic ice, was completed. IceCube now consists of an array of 5160 digital light detection modules assembled on 86 strings, which encloses a instrumented volume of roughly 1~km$^3$ optimized for detection of neutrinos down to energies of 100~GeV.

8. Dark Matter in the Solar System, Galaxy, and Beyond
Sammanfattning : There is evidence that dark matter constitutes a majority of the Universe's matter content. Yet, we are ignorant about its nature. Understanding dark matter requires new physics, possibly in the form of a new species of fundamental particles. LÄS MER
9. A search for solar dark matter with the IceCube neutrino detector : Advances in data treatment and analysis technique
Sammanfattning : There is compelling observational evidence for the existence of dark matter in the Universe, including our own Galaxy, which could possibly consist of weakly interacting massive particles (WIMPs) not contained in the standard model (SM) of particle physics. WIMPs may get gravitationally trapped inside heavy celestial bodies of ordinary matter. LÄS MER
10. A Search for Solar Neutralino Dark Matter with the AMANDA-II Neutrino Telescope
Sammanfattning : A relic density of Weakly Interacting Massive Particles (WIMPs) remaining from the Big Bang constitutes a promising solution to the Dark Matter problem. It is possible for such WIMPs to be trapped by and accumulate in gravitational potentials of massive dense objects such as the Sun. LÄS MER
