  2. 6. Search for Weakly Produced Supersymmetric Particles in the ATLAS Experiment

    Author : Maja Tylmad; Christophe Clément; Barbro Åsman; Patrice Verdier; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ATLAS; ATLAS experiment; supersymmetry; chargino; neutralino; physics analysis; LHC; Large Hadron Collider; fysik; Physics;

    Abstract : The Large Hadron Collider located at CERN is currently the most powerful particle accelerator and ATLAS is an experiment designed to exploit the high energy proton-proton collisions provided by the LHC. It opens a unique window to search for new physics at very high energy, such as supersymmetry, a postulated symmetry between fermions and bosons. READ MORE

  4. 7. Indirect Detection of Neutralino Dark Matter

    Author : Piero Ullio; Marc Kamionkowski; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical Physics; teoretisk fysik;

    Abstract : The detection of dark matter is a primary issue in today's astrophysics. Although the lightest supersymmetric particle, generally assumed to be a neutralino, is an excellent dark matter candidate, it is not easy to prove that such particles are the main component of galactic halos.

  5. 8. Serch for Neutralino Dark Matter with the AMANDA-II Neutrino Telescope

    Author : Yulia Minaeva; Per Olof Hulth; John Carr; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Elementary particle physics; Elementarpartikelfysik;

    Abstract : The annihilation of weakly interacting massive particles (WIMPs), accumulated in gravitational potentials (e.g., the core of the Earth, the Sun or the Galactic halo) would lead to neutrino production. READ MORE

  6. 9. A search for neutralino dark matter with the AMANDA-B10 detector

    Author : Eva Dalberg; Yves Sacquin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Abstract : If supersymmetric particles in the form of neutralinos are part of the dark matter halo in our Galaxy, they can accumulate gravitationally in the center of the Earth and pair-wise annihilate therein. Such annihilations can be observed as an excess signal of vertical up-moving neutrino induced muon tracks in a neutrino detector like AMANDA. READ MORE

  7. 10. A Dark Matter Search with AMANDA : Limits on the Muon Flux from Neutralino Annihilations at the Centre of the Earth with 1997-99 Data

    Author : Patrik Ekström; Per Olof Hulth; Lee Thompson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Elementary particle physics; Elementarpartikelfysik;

    Abstract : The nature of the dark matter in the Universe is one of the greatest mysteries in modern astronomy. The neutralino is a nonbaryonic dark matter candidate in minimal supersymmetric extensions to the standard model of particle physics. READ MORE
