  2. 11. 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

  4. 12. Searching for an Ultra High-Energy Diffuse Flux of Extraterrestrial Neutrinos with IceCube 40

    Author : Henrik Johansson; Christian Walck; Antoine Letessier-Selvon; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Neutrinos; UHE; diffuse; IceCube; Astroparticle physics; Astropartikelfysik; fysik; Physics;

    Abstract : Neutrino astronomy has the potential to greatly improve our understanding of the high-energy universe. An unresolved, diffuse, flux of neutrinos is sensitive to the properties of the population of cosmic accelerators in the universe. READ MORE

  5. 13. Isospin Breaking in Kaon Decays to Pions

    Author : Fredrik Borg; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Elementary particle physics; termodynamik; statistisk fysik; gravitation; relativitet; kvantmekanik; thermodynamics; Matematisk och allmän teoretisk fysik; Pseudo-scalar meson; Isospin Breaking; Chiral Perturbation Theory; Mathematical and general theoretical physics; classical mechanics; quantum mechanics; relativity; statistical physics; Weak Interaction; Strong Interaction; kvantfältteori; High energy interactions; Kärnfysik; Nuclear physics; klassisk mekanik; quantum field theory; cosmic rays; Kosmisk strålning; högenergi; Elementarpartikelfysik;

    Abstract : The five different K -> 3 Pi and the three K -> 2 Pi decays are calculated in Chiral Perturbation Theory. The calculation is done using different approximations, to study whether this changes the result significantly. First the isospin approximation is used. Discrepancies are then found between theory and experiment. READ MORE

  6. 14. Electric Energy Conversion Systems : Wave Energy and Hydropower

    Author : Karin Thorburn; Mats Leijon; Petra Lundström; Uppsala universitet; []
    Keywords : Engineering physics; Ocean wave power; renewable energy; linear generator; farm simulation; Teknisk fysik;

    Abstract : Electric energy conversion is an important issue in today's society as our daily lives largely depend on the supplies of energy. Two energy sources are studied for conversion in the present thesis, ocean waves and hydropower. The work focuses on the generator and the transmission of its output to the electric grid. READ MORE

  7. 15. Investigations on Emission Sources in Proton-Nucleus and Nucleus-Nucleus Collisions

    Author : Johan Mårtensson; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; High energy interactions; Fysik; Physics; correlation function.; fermion interferometry; t p and d p ratios; target mass dependence; pion angular distribution; pion excitation function; Heavy ion reactions; intermediate energy; cosmic rays; Kosmisk strålning; högenergi;

    Abstract : Emission sources in proton-nucleus and nucleus-nucleus collisions at intermediate energies have been studied. Pion excitation functions from the absolute threshold to 500 MeV have been measured with an ion beam of continuously varying energy with an energy resolution of 1 MeV. READ MORE
