6. Weigh them all! : Cosmological searches for the neutrino mass scale and mass ordering
Sammanfattning : The elusive neutrinos are among the most intriguing constituents of the particle zoo. The observation of neutrino flavour oscillations, indicating that neutrinos are massive, provides the only direct evidence for physics beyond the Standard Model. LÄS MER
7. 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
8. Predictions of Effective Models in Neutrino Physics
Sammanfattning : Experiments on neutrino oscillations have confirmed that neutrinos have small, but non-zero masses, and that the interacting neutrino states do not have definite masses, but are mixtures of such states.The seesaw models make up a group of popular models describing the small neutrino masses and the corresponding mixing. LÄS MER
9. Phenomenology of SO(10) Grand Unified Theories
Sammanfattning : Although the Standard Model (SM) of particle physics describes observations well, there are several shortcomings of it. The most crucial of these are that the SM cannot explain the origin of neutrino masses and the existence of dark matter. LÄS MER
10. Searching for dark matter in the Galactic Halo with IceCube using high energy cascades
Sammanfattning : The presence of dark matter is inferred at scales ranging from rotations of galaxies to imprints in the CMB – the Big Bang after-glow. The nature of dark matter is, however, still unknown as no detection other than the gravitational one has been made. LÄS MER
