1. 16. Dark Matter in the Milky Way

   Författare :Axel Widmark; Joakim Edsjö; David Milstead; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dark matter; Theoretical Physics; teoretisk fysik;

   Sammanfattning : Den här licenciatuppsatsen bygger på två vetenskapliga artiklar, varav den första är skriven som ensamförfattare och den andra är skriven tillsammans med Dr. Giacomo Monari. De är båda på temat mörk materia i Vintergatan.Den första artikeln handlar om mörk materia som fångas i solen. LÄS MER

3. 17. Light from Dark Matter : Hidden Dimensions, Supersymmetry, and Inert Higgs

   Författare :Michael Gustafsson; Lars Bergström; Steen Hannestad; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Theoretical Physics; teoretisk fysik;

   Sammanfattning : Recent observational achievements within cosmology and astrophysics have lead to a concordance model in which the energy content in our Universe is dominated by presumably fundamentally new and exotic ingredients – dark energy and dark matter. To reveal the nature of these ingredients is one of the greatest challenges in physics. LÄS MER

4. 18. Calibration of b-tagging and search for Dark Matter : Calibration of b-tagging efficiency and search for Dark Matter production in association with heavy flavour quarks with the ATLAS experiment

   Författare :Anna Shcherbakova; Sara Strandberg; Oscar Gonzalez Lopez; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ATLAS; ATLAS experiment; physics analysis; LHC; Large Hadron Collider; Dark Matter; b-tagging; fysik; Physics;

   Sammanfattning : The Large Hadron Collider (LHC) is the most powerful and complex particle accelerator ever built. The ATLAS and the CMS are the two multipurpose particle detectors at the LHC, designed to cover a wide range of physics measurements. LÄS MER

5. 19. Dark matter electron interactions in detector materials

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

   Sammanfattning : 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. Studying DM in the lab is key to understanding its nature. LÄS MER

7. 20. Studies of dark matter in and around stars

   Författare :Sofia Sivertsson; Tommy Ohlsson; Joakim Edsjö; Gianfranco Bertone; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dark matter; particle astrophysics;

   Sammanfattning : There is by now compelling evidence that most of the matter in the Universe is in the form of dark matter, a form of matter quite different from the matter we experience in every day life. The gravitational effects of this dark matter have been observed in many different ways but its true nature is still unknown. LÄS MER
