listelement.badge.dso-type Kirje , Neutrino Physics beyond the Standard Model(2008-07-07T06:02:09Z) Hektor, AndiThis thesis links together a set of publications from the dissertant, which are devoted to neutrino physics in general. The work is focused on different neutrino related topics: neutrino physics in the context of cosmology and general particle physics, the mechanisms of neutrino mass generation and the properties of the different neutrino models and leptogenesis. The thesis starts with a short description of particle physics and cosmology. Chapter 3 focused on experimental and observational effects beyond the Standard Model. The next chapter described some neutrino models beyond the Standard Model. The three mechanisms for neutrino mass were described: type I, II and II see-saw. In addition, CP-violation in the neutrino sector and the running of neutrino parameters were discussed. Chapter 5 introduced leptogenesis. The type I leptogenesis was presented as a most popular example of leptogenesis. Also, some short notes were made for the type II leptogenesis. The publications related to the thesis are summarized in the following separate chapter.
