    Sammanfattning : The identity of dark matter is one of the key outstanding problems in both particle and astrophysics. In this thesis, I describe a number of complementary searches for particle dark matter. LÄS MER

  2. 2. Searches for Dark Matter with IceCube and DeepCore New constraints on theories predicting dark matter particles

    Detta är en avhandling från Stockholm : Department of Physics, Stockholm University

    Författare :Matthias Danninger; Stockholms universitet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dark matter; neutrinos; neutrino telescopes; IceCube; DeepCore; dark matter experiments; Physics; fysik;

    Sammanfattning : The cubic-kilometer sized IceCube neutrino observatory, constructed in the glacial ice at the South Pole, searches indirectly for dark matter via neutrinos from dark matter self-annihilations. It has a high discovery potential through striking signatures. LÄS MER

  3. 3. Supersymmetric Dark Matter aspects of sfermion coannihilations

    Detta är en avhandling från Stockholm : Fysikum

    Författare :Mia Schelke; Stockholms universitet.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Supersymmetry; Dark Matter; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Sammanfattning : There is very strong evidence that ordinary matter in the Universe is outweighed by almost ten times as much so-called dark matter. Dark matter does neither emit nor absorb light and we do not know what it is. LÄS MER

  4. 4. Cosmological Dark Matter and the Isotropic Gamma-Ray Background Measurements and Upper Limits

    Detta är en avhandling från Stockholm : Department of Physics, Stockholm University

    Författare :Alexander Sellerholm; Stockholms universitet.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dark matter theory; dark matter simulations; dark matter experiments; isotropic gamma-ray background; Fermi gamma-ray space telescope; NATURAL SCIENCES Physics Astronomy and astrophysics Astroparticle physics; NATURVETENSKAP Fysik Astronomi och astrofysik Astropartikelfysik; Theoretical Physics; teoretisk fysik;

    Sammanfattning : This thesis addresses the isotropic diffuse gamma-ray background, as measured by the Fermi gamma ray space telescope, and its implications for indirect detection of dark matter. We describe the measurement of the isotropic background, including also an alternative analysis method besides the one published by the Fermi-LAT collaboration. LÄS MER

  5. 5. Phenomenology of Inert Scalar and Supersymmetric Dark Matter

    Detta är en avhandling från Stockholm : Department of Physics, Stockholm University

    Författare :Erik Lundström; Stockholms universitet.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Dark matter; inert scalars; supersymmetry; indirect detection; accelerator searches; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik; NATURAL SCIENCES Physics Elementary particle physics Astroparticle physics; NATURVETENSKAP Fysik Elementarpartikelfysik Astropartikelfysik; NATURAL SCIENCES Physics Elementary particle physics; NATURVETENSKAP Fysik Elementarpartikelfysik; teoretisk fysik; Theoretical Physics;

    Sammanfattning : While the dark matter has so far only revealed itself through the gravitational influence it exerts on its surroundings, there are good reasons to believe it is made up by WIMPs – a hypothetical class of heavy elementary particles not encompassed by the Standard Model of particle physics.The Inert Doublet Model constitutes a simple extension of the Standard Model Higgs sector.
