  2. 1. Supersymmetric Dark Matter : aspects of sfermion coannihilations

    Author : Mia Schelke; Joakim Edsjö; Nicolao Fornengo; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Supersymmetry; Dark Matter; Physics; Fysik;

    Abstract : 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. READ MORE

  4. 2. Dark matter electron interactions in detector materials

    Author : Einar Urdshals; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; effective theory; Dark matter; direct detection;

    Abstract : Dark Matter (DM) makes up 85% of the matter content of the universe, and its gravitational effects are seen on scales ranging from that of cosmology to that of galactic astrophysics. The nature of DM is, however, unknown. READ MORE

  5. 3. Cosmological Dark Matter and the Isotropic Gamma-Ray Background : Measurements and Upper Limits

    Author : Alexander Sellerholm; Jan Conrad; Karl Mannheim; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dark matter theory; dark matter simulations; dark matter experiments; isotropic gamma-ray background; Fermi gamma-ray space telescope; Astroparticle physics; Astropartikelfysik; teoretisk fysik; Theoretical Physics;

    Abstract : 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. READ MORE

  6. 4. Inference on Dark Matter in Effective Field Theories : From XENON1T towards XENONnT: Chiral effective field theory analysis of nuclear recoils, single electrons and uncommon background modelling

    Author : Vasile Cristian Antochi; Jan Conrad; Björn Penning; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dark Matter; Direct Detection; Effective Field Theory; Chiral Effective Field Theory; Physics; fysik;

    Abstract : Cosmological and astronomical observations show that most of the matter in the Universe is dark. This dissertation provides an overview of the dark matter evidence, and focuses on the particle dark matter hypothesis, describing possible particle candidates, concentrating on the Weakly Interactive Massive Particles (WIMPs).

  7. 5. Unveiling the nature of dark matter with direct detection experiments

    Author : Vanessa Zema; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NaI; phenomenology; annual-modulation; direct-detection; cryogenics; COSINUS; polarised-nuclei; CRESST; dark-matter; phonons;

    Abstract : The desire of discovery is an anthropic need which characterises and connects the human being over the eras. In particular, observing the sky is an instinctive drive exerted by the curiosity of the mysteries which it retains. READ MORE
