  2. 16. Dynamics of quarks and leptons : theoretical Studies of Baryons and Neutrinos

    Author : Tommy Ohlsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chiral quark model; baryons; conguration mixing; magnetic moments; Coleman{Glashow sum-rule; spin structure; spin polarizations; weak form factors; semileptonic decays; nucleon quark sea isospin asymmetry; neutrinos; neutrino oscillations; neutrino avors; mixing angles; mass squared dierences; MSW eect; numerical calculations; interpretation of experiments; Mathematical physics; Matematisk fysik;

    Abstract : The Standard Model of Elementary Particle Physics (SM) is the present theoryfor the elementary particles and their interactions and is a well-established theorywithin the physics community. The SM is a combination of Quantum Chromodynamics(QCD) and the Glashow{Weinberg{Salam (GWS) electroweak model. READ MORE

  4. 17. Extending the observational reach of core-collapse supernovae for IceCube using high-energy neutrinos

    Author : Nora Valtonen-Mattila; Erin O'Sullivan; Timothy Linden; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Neutrino physics; Neutrino astrophysics; Supernovae; Core-collapse supernovae; Particle astrophysics; Fysik; Physics;

    Abstract : Neutrino telescopes such as IceCube monitor for low-energy neutrinos O(10 MeV) produced in nuclear processes during core-collapse in supernovae. The detection horizon to the neutrino burst is 50 kpc, the distance to the Magellanic Clouds. READ MORE

  5. 18. Search for low mass WIMPs with the AMANDA neutrino telescope

    Author : Anna Davour; Olga Botner; Carlos de los Heros; Mark Pearce; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; dark matter; WIMP; neutrino detection; AMANDA; supersymmetry; Fysik; Physics; Fysik; High Energy Physics; Högenergifysik;

    Abstract : Recent measurements show that dark matter makes up at least one fifth of the total energy density of the Universe. The nature of the dark matter is one of the biggest mysteries in current particle physics and cosmology. READ MORE

  6. 19. Searching for dark matter in the Galactic Halo with IceCube using high energy cascades

    Author : Samuel Flis; Klas Hultqvist; Chad Finley; Emmanuel Moulin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; IceCube; neutrino; dark matter; halo; Milky Way; fysik; Physics;

    Abstract : The presence of dark matter is inferred at scales ranging from rotations of galaxies to imprints in the CMB – the Big Bang after-glow. The nature of dark matter is, however, still unknown as no detection other than the gravitational one has been made. READ MORE

  7. 20. 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
