2. 11. Exploring the Universe Using Neutrinos : A Search for Point Sources in the Southern Hemisphere Using the IceCube Neutrino Observatory

   Author : Rickard Ström; Allan Hallgren; Olga Botner; Chad Finley; Lawrence R. Sulak; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; astroparticle physics; neutrino sources; neutrino telescopes; IceCube; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

   Abstract : Neutrinos are the ideal cosmic messengers, and can be used to explore the most powerful accelerators in the Universe, in particular the mechanisms for producing and accelerating cosmic rays to incredible energies. By studying clustering of neutrino candidate events in the IceCube detector we can discover sites of hadronic acceleration. READ MORE

4. 12. Neutrino Oscillations and Charged Higgs Bosons – Experimental Projects for Physics beyond the Standard Model

   Author : Christian Hansen; Tord Ekelöf; Blair Ratcliff; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Elementary particle physics; CERN; LHC; ATLAS; charged; Higgs; SUSY; MSSM; oscillating; neutrino; RICH; CNGS; HPD; Elementarpartikelfysik; Elementary particle physics; Elementarpartikelfysik;

   Abstract : This thesis is based on work done in two different experimental projects. The first project, the Tau RICH, is a previously proposed τ-neutrino appearance experiment for the CERN neutrino beam at the Gran Sasso laboratory in Italy. The proposed experimental concept is based on the use of focusing RICH detectors with liquid radiator (C6F14). READ MORE

5. 13. Weigh them all! : Cosmological searches for the neutrino mass scale and mass ordering

   Author : Sunny Vagnozzi; Katherine Freese; Lars Bergström; Alessandra Silvestri; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; neutrinos; neutrino mass; neutrino mass ordering; cosmology; cosmic microwave background; large-scale structure; galaxy surveys; dark energy; cosmic inflation; data analysis; teoretisk fysik; Theoretical Physics;

   Abstract : 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. READ MORE

6. 14. Indirect Searches for Dark Matter in the Milky Way with IceCube-DeepCore

   Author : Martin Wolf; Chad Finley; Maurizio Spurio; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dark Matter Annihilation; WIMP; Milky Way; IceCube Neutrino Observatory; DeepCore; neutrino; particle physics; high-energy physics; fysik; Physics;

   Abstract : 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. READ MORE

7. 15. Predictions of Effective Models in Neutrino Physics

   Author : Johannes Bergström; Tommy Ohlsson; Rikard Enberg; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Neutrino mass; lepton mixing; Majorana neutrinos; effective field theory; Weinberg operator; seesaw models; low-scale seesaw models; inverse seesaw; right-handed neutrinos; renormalization group; threshold effects; neutrinoless double beta decay; Elementary particle physics; Elementarpartikelfysik;

   Abstract : 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.
