  2. 1. Matter and damping effects in neutrino mixing and oscillations

    Author : Mattias Blennow; Tommy Ohlsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; Neutrino oscillations; neutrino mixing; matter effects; damping effects; the day-night effect; solar neutrinos; Teknisk fysik; Engineering physics; Teknisk fysik;

    Abstract : This thesis is devoted to the study of neutrino physics in general and the study of neutrino mixing and oscillations in particular. In the standard model of particle physics, neutrinos are massless, and as a result, they do not mix or oscillate. READ MORE

  4. 2. Theoretical and Phenomenological Studies of Neutrino Physics

    Author : Mattias Blennow; Tommy Ohlsson; Eligio Lisi; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; neutrino mass; neutrino mixing; neutrino oscillations; matter effects; non-standard effects; the day-night effect; solar neutrinos; accelerator neutrinos; exact solutions; three-flavor effects; large density; neutrino decay; neutrino decoherence; neutrino absorption; non-standard neutrino interactions; seesaw mechanism; stability criteria; leptogenesis; Physics; Fysik;

    Abstract : This thesis is devoted to the theory and phenomenology of neutrino physics. While the standard model of particle physics has been extremely successful, it fails to account for massive neutrinos, which are necessary to describe the observations of neutrino oscillations made by several different experiments.

  5. 3. Dark Matter Phenomenology in Astrophysical Systems

    Author : Stefan Clementz; Mattias Blennow; Kai Schmidt-Hoberg; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik; Physics;

    Abstract : There is now a great deal of evidence in support of the existence of a large amount of unseen gravitational mass, commonly called dark matter, from observations in astrophysical systems of sizes ranging from that of dwarf galaxies to the scale of the entire Universe. One of the most promising explanations for this unseen mass is that it consists of a species of unobserved elementary particles. READ MORE

  6. 4. Effects of Dark Matter in Astrophysical Systems

    Author : Stefan Clementz; Mattias Blennow; Tommy Ohlsson; Riccardo Catena; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dark matter; Self-interactions; solar capture; helioseismology; inelastic dark matter; direct detection; indirect detection; Fysik; Physics;

    Abstract : When studying astrophysical structures with sizes ranging from dwarf galaxies to galaxy clusters, it becomes clear that there are vast amounts of unobservable gravitating mass. A compelling hypothesis is that this missing mass, which we call dark matter, consists of elementary particles that can be described in the same manner as those of the standard model of particle physics.

  7. 5. Studies of effective theories beyond the Standard Model

    Author : Stella Riad; Tommy Ohlsson; Mattias Blennow; Johan Rathsman; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Effective field theories; neutrino physics; extra dimensions; universal extra dimensions; Higgs physics; renormalization group running; Bayesian statistics; coupling scale factor; grand unified theories;

    Abstract : The vast majority of all experimental results in particle physics can be described by the Standard Model (SM) of particle physics. However, neither the existence of neutrino masses nor the mixing in the leptonic sector, which have been observed, can be described within this model. READ MORE
