16. Dynamics of quarks and leptons : theoretical Studies of Baryons and Neutrinos
Sammanfattning : The Standard Model of Elementary Particle Physics (SM) is the present theoryfor the elementary particles and their interactions and is a well-established theorywithin the physics community. The SM is a combination of Quantum Chromodynamics(QCD) and the Glashow{Weinberg{Salam (GWS) electroweak model. LÄS MER
17. Extending the observational reach of core-collapse supernovae for IceCube using high-energy neutrinos
Sammanfattning : Neutrino telescopes such as IceCube monitor for low-energy neutrinos O(10 MeV) produced in nuclear processes during core-collapse in supernovae. The detection horizon to the neutrino burst is 50 kpc, the distance to the Magellanic Clouds. LÄS MER
18. 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
19. 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
20. A search for solar dark matter with the IceCube neutrino telescope
Sammanfattning : Dark matter particles in the form of supersymmetric Weakly Interacting Massive Particles (WIMPs) could accumulate in the centre of the Sun because of gravitational trapping. Pair-wise annihilations of WIMPs could create standard model particles out of which neutrinos could reach the Earth. LÄS MER
