    Abstract : 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. READ MORE

  2. 2. A Search for Solar Neutralino Dark Matter with the AMANDA-II Neutrino Telescope

    University dissertation from Stockholm : Fysikum

    Author : Thomas Burgess; Stockholms universitet.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dark matter; AMANDA; Supersymmetry; WIMP; Neutralino; Neutrino; IceCube; Astroparticle physics; NATURAL SCIENCES Physics Astronomy and astrophysics Astroparticle physics; NATURVETENSKAP Fysik Astronomi och astrofysik Astropartikelfysik; Physics; fysik;

    Abstract : A relic density of Weakly Interacting Massive Particles (WIMPs) remaining from the Big Bang constitutes a promising solution to the Dark Matter problem. It is possible for such WIMPs to be trapped by and accumulate in gravitational potentials of massive dense objects such as the Sun. READ MORE

  3. 3. Search for Subrelativistic Particles with the AMANDA Neutrino Telescope

    University dissertation from Uppsala : Uppsala University Library

    Author : Arvid Pohl; Högskolan i Kalmar.; Uppsala universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Physics Astronomy and astrophysics Astroparticle physics; NATURVETENSKAP Fysik Astronomi och astrofysik Astropartikelfysik; Astroparticle Physics; Astropartikelfysik; NATURAL SCIENCES Physics Elementary particle physics Astroparticle physics; NATURVETENSKAP Fysik Elementarpartikelfysik Astropartikelfysik;

    Abstract : AMANDA is a neutrino telescope situated at the geographical South Pole. The detection method is based on Cherenkov radiation from muons that are created when muon neutrinos collide with atomic nuclei near the detector. The main part of the detector is an array of 677 PMT in the ice at a depth of 1500 - 2000 m. READ MORE

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

    University dissertation from Stockholm : Department of Physics, Stockholm University

    Author : Erik Lundström; Stockholms universitet.; [2010]
    Keywords : 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;

    Abstract : 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.

  5. 5. Accelerators for Physics Experiments From Diagnostics and Control to Design

    University dissertation from Stockholm : KTH

    Author : Elena Wildner; KTH.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Physics Elementary particle physics Astroparticle physics; NATURVETENSKAP Fysik Elementarpartikelfysik Astropartikelfysik;

    Abstract : This thesis develops techniques of control-methods, optimization, and diagnostics of accelerator equipment and the produced particle beams with emphasis on the Large Hadron Collider (LHC) project at CERN. From a solid knowledge of the characteristics of the manufactured accelerator equipment gained from in-depth measurements and analysis of measured data, a link to an enhanced equipment design can be made.
