  1. 1. Sjukskrivnas arbetsbörda : Arbetande medborgare möter en kundorienterad byråkrati

    Författare :Johan Kaluza; Per Skålén; Johan Quist; Martin Fransson; Mikael Holmqvist; Karlstads universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Working citizen; Bureaucratic co-creation; Practice theory; Customer-oriented bureaucracy; Working consumers; Public administration; Arbetande medborgare; Byråkratiskt samskapande; Kundorienterad byråkrati; Praktikteori; Offentlig sektor; Sjukförsäkring; Business Administration; Företagsekonomi;

    Sammanfattning : Denna avhandling är baserad på en empirisk studie av Försäkringskassan. Teoretiskt tar avhandlingen sitt avstamp i litteraturen om arbetande konsumenter och kundorienterade byråkratier. LÄS MER

  3. 2. A Search for Dark Matter in the Sun with AMANDA and IceCube

    Författare :Olle Engdegård; Olga Botner; Allan Hallgren; Jodi Cooley; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dark matter; WIMP; neutralino; MSSM; Kaluza-Klein; IceCube; AMANDA; neutrino telescope; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Sammanfattning : A search for weakly interacting massive particles (WIMPs) annihilating in the Sun was performed with the IceCube and AMANDA neutrino telescopes, using data from 2008 corresponding to 149 days of livetime. Assuming that particles in the dark matter halo scatter and accumulate in the centre of the Sun, Majorana WIMPs may pair-wise annihilate and give rise to a neutrino signal detectable in an experiment at Earth.

  4. 3. Yang-Mills Theory in Gauge-Invariant Variables and Geometric Formulation of Quantum Field Theories

    Författare :Sergey Slizovskiy; Antti Niemi; Andrey Losev; Andrey Marshakov; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Yang-Mills theory; spin-charge separation; Kaluza-Klein theory; branes; curved beta-gamma systems; Mathematical physics; Matematisk fysik; Theoretical Physics; Teoretisk fysik;

    Sammanfattning : In Part I we are dealing with effective description of Yang-Mills theories based on gauge-invarint variables. For pure Yang-Mills we study the spin-charge separation varibles. The dynamics in these variables resembles the Skyrme-Faddeev model. LÄS MER

  5. 4. Astrophysical and Collider Signatures of Extra Dimensions

    Författare :Henrik Melbéus; Tommy Ohlsson; Jörn Kersten; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Extra-dimensional quantum field theories; universal extra dimensions; Kaluza-Klein dark matter; Arkani-Hamed-Dimopoulos-Dvali model; hierarchy problem; neutrino mass; seesaw mechanism; Large Hadron Collider phenomenology; Elementary particle physics; Elementarpartikelfysik;

    Sammanfattning : In recent years, there has been a large interest in the subject of extra dimensions in particle physics. In particular, a number of models have been suggested which provide solutions to some of the problems with the current Standard Model of particle physics, and which could be tested in the next generation of high-energy experiments.

  7. 5. Particle Phenomenology of Compact Extra Dimensions

    Författare :Henrik Melbéus; Tommy Ohlsson; Andrea Romanino; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Higher-dimensional quantum field theories; universal extra dimensions; Arkani-Hamed–Dimopolous–Dvali ADD model; hierarchy problem; Kaluza– Klein dark matter; neutrino mass; seesaw mechanism; leptonic mixing; renormalization group running; collider phenomenology; Large Hadron Collider;

    Sammanfattning : This thesis is an investigation of the subject of extra dimensions in particle physics. In recent years, there has been a large interest in this subject. In particular, a number of models have been suggested that provide solutions to some of the problem with the current Standard Model of particle physics. LÄS MER
