  2. 16. A search for solar dark matter with the IceCube neutrino telescope

    Author : Gustav Wikström; Klas Hultqvist; John Carr; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dark matter; neutrinos; neutrino telescopes; IceCube; Astroparticle physics; Astropartikelfysik; fysik; Physics;

    Abstract : Dark matter particles in the form of supersymmetric Weakly Interacting Massive Particles (WIMPs) could accumulate in the centre of the Sun because of gravitational trapping. Pair-wise annihilations of WIMPs could create standard model particles out of which neutrinos could reach the Earth. READ MORE

  4. 17. Color Screening in QCD and Neutrinos from Singlino Dark Matter

    Author : Dominik Werder; Gunnar Ingelman; Rikard Enberg; Roman Pasechnik; Hannes Jung; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; QCD; Diffraction; SCI; Dark Matter; Singlino; NMSSM; Indirect Detection; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Abstract : Hard diffraction in proton collisions, where the initial state proton emerges from the interaction rather undisturbed despite a hard interaction scale, has been studied for a few decades. First observed in proton-proton collisions, the phenomenon is seen as well in deep inelastic electron-proton scattering (DIS) as a leading final state proton and a rapidity gap-region without final state particles.

  5. 18. Searches for supersymmetric long-lived particles with displaced-vertex signatures and studies of the electronic noise in the Tile Calorimeter at the ATLAS experiment

    Author : Filip Backman; David Milstead; Christian Ohm; Stefan Richter; Sten Hellman; Kenneth Österberg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Abstract : The Standard Model of particle physics is successful at describing nature on the smallest scales, but it has known flaws. These can be remedied by extended theories, such as supersymmetry. A quantum number in the supersymmetry framework is R-parity. This quantity is generally conserved, but can be violated. READ MORE

  6. 19. Cosmological aspects of universal extra dimensions

    Author : Torsten Bringmann; Lars Bergström; Pierre Binetruy; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cosmology; dark matter; extra dimensions; Cosmology; Kosmologi;

    Abstract : It is an intriguing possibility that our world may consist of more than three spatial dimensions, compactified on such a small scale that they so far have escaped detection. In this thesis, a particular realization of this idea -- the scenario of so-called 'universal extra dimensions' (UED) -- is studied in some detail, with a focus on cosmological consequences and appplications.

  7. 20. Search for Charginos and Sleptons in ATLAS and Identification of Pile-up with the Tile Calorimeter

    Author : Pawel Klimek; Christophe Clément; Jan Conrad; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LHC; ATLAS; TileCal; Supersymmetry; Quality Factor; fysik; Physics;

    Abstract : The Large Hadron Collider (LHC) located at the European Organization for Nuclear Research (CERN) is the most powerful particle accelerator in the world in terms of collision energy and luminosity. This thesis presents a search for supersymmetric particles in proton-proton collision data recorded by the ATLAS experiment. READ MORE
