  1. 1. Searches for Particle Dark Matter : Dark stars, dark galaxies, dark halos and global supersymmetric fits

    Författare :Pat Scott; Joakim Edsjö; Lars Bergström; Jan Conrad; Dan Hooper; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; dark matter; supersymmetry; gamma rays; dwarf galaxies; stellar evolution; cosmological perturbations; phase transitions; statistical techniques; Astroparticle physics; Astropartikelfysik; Astroparticle physics; Astropartikelfysik; Cosmology; Kosmologi; Elementary particle physics; Elementarpartikelfysik; Computational physics; Beräkningsfysik; Formation and development of stars; Stjärnors bildning och utveckling; High energy astrophysics; Högenergiastrofysik; Theoretical Physics; teoretisk fysik;

    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. Black holes and trapped surfaces

    Författare :Emma Jakobsson; Ingemar Bengtsson; István Rácz; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Theoretical Physics; teoretisk fysik;

    Sammanfattning : The study of black holes is an important part of general relativity. However, the very definition of black holes is not completely satisfactory. Alternative definitions are based on the concept of trapped surfaces. This licentiate thesis is based on work with the aim to better understand the behaviour of such trapped surfaces. LÄS MER

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

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

    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. LÄS MER

  4. 4. From Branes to Brains : On M-theory and Understanding Thermodynamics

    Författare :Tom W. Adawi; Jon Ogborn; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Physics; M-theory; p-branes; supersymmetry; duality; heat and temperature; phenomenography; context; Physics Education Research; Fysik; Fysikens didaktik; Physics; Fysik; Materiefysik; Physics of Matter; Physics with specialization in Physics Education; Fysik med inriktning mot fysikens didaktik;

    Sammanfattning : This thesis is concerned with research in both physics and physics education, and is divided into two parts.Part IString theory has been the leading candidate over the past few years for a theory that unifies all the fundamental forces of nature. LÄS MER

  5. 5. 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 :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; ATLAS; ATLAS experiment; physics analysis; LHC; Large Hadron Collider; Dark Matter; b-tagging; Physics; fysik;

    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
