1. WIMP searches in an Effective Field Theory Framework from XENON1T to XENONnT
Sammanfattning : Observations from cosmology and astronomy suggest that most of the matter in the Universe is comprised of dark matter. In this thesis the evidence for dark matter and the possible candidates are explored, focusing on the Weakly Interacting Massive Particles (WIMPs) hypothesis. LÄS MER
2. Indirect Searches for Dark Matter in the Milky Way with IceCube-DeepCore
Sammanfattning : Many astronomical observations, including rotational curve measurements of stars and the analysis of the cosmic microwave background, suggest the existence of an invisible matter density content in the Universe, commonly called Dark Matter (DM). Possibly, DM could be of particle nature, where Weakly Interacting Massive Particles (WIMPs) could be a viable DM candidate. LÄS MER
3. Dark Matter in the Galactic Halo : A Search Using Neutrino Induced Cascades in the DeepCore Extension of IceCube
Sammanfattning : A search for Weakly Interacting Massive Particles (WIMPs) annihilating in the dark matter halo of the Milky Way was performed, using data from the IceCube Neutrino Observatory and its low-energy extension DeepCore. The data were collected during one year between 2011 to 2012 corresponding to 329.1 days of detector livetime. LÄS MER
4. A Search for Dark Matter in the Sun with AMANDA and IceCube
Sammanfattning : A search for weakly interacting massive particles (WIMPs) annihilating in the Sun was performed with the IceCube and AMANDA neutrino telescopes, using data from 2008 corresponding to 149 days of livetime. Assuming that particles in the dark matter halo scatter and accumulate in the centre of the Sun, Majorana WIMPs may pair-wise annihilate and give rise to a neutrino signal detectable in an experiment at Earth.

5. Search for low mass WIMPs with the AMANDA neutrino telescope
Sammanfattning : Recent measurements show that dark matter makes up at least one fifth of the total energy density of the Universe. The nature of the dark matter is one of the biggest mysteries in current particle physics and cosmology. LÄS MER
