  1. 1. A search for ultra-high energy neutrinos with AMANDA-II

    University dissertation from Stockholm : Fysikum

    Author : Christin Wiedemann; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Neutrinos; Cosmic rays; Ultra-high energy; AMANDA; IceCube; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik; Physics; fysik;

    Abstract : High-energy neutrinos are capable of carrying information over vast distances, and neutrino telescopes such as AMANDA-II provide the means to probe deep inside the violent and energetic interior of the universe. AMANDA-II is located in the glacial ice at South Pole in Antarctica and is optimised to detect Cherenkov emission from neutrino-induced muon tracks with energies above 100 GeV. READ MORE

  2. 2. On the Search for High-Energy Neutrinos Analysis of data from AMANDA-II

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Johan Lundberg; Uppsala universitet.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; neutrinos; neutrino detection; cosmic rays; ultra-high energy; numerical simulation; optical properties; monte carlo method; ray tracing; neutrino detection; AMANDA; IceCube; WIMP; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Abstract : A search for a diffuse flux of cosmic neutrinos with energies in excess of 1014 eV was performed using two years of AMANDA-II data, collected in 2003 and 2004. A 20% evenly distributed sub-sample of experimental data was used to verify the detector description and the analysis cuts. READ MORE

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

    University dissertation from Stockholm : Department of Physics, Stockholm University

    Author : Henrik Johansson; Stockholms universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Neutrinos; UHE; diffuse; IceCube; NATURAL SCIENCES Physics Astronomy and astrophysics Astroparticle physics; NATURVETENSKAP Fysik Astronomi och astrofysik 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

  4. 4. Physics at the High-Energy Frontier Phenomenological Studies of Charged Higgs Bosons and Cosmic Neutrino Detection

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Oscar Stål; Uppsala universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; particle physics; Standard Model; beyond the Standard Model; supersymmetry; Higgs physics; charged Higgs boson; LHC; flavour physics; ultra-high-energy neutrinos; Askaryan effect; radio detection; lunar satellites; NATURAL SCIENCES Physics Elementary particle physics; NATURVETENSKAP Fysik Elementarpartikelfysik; högenergifysik; High Energy Physics;

    Abstract : The Standard Model of particle physics successfully describes present collider data. Nevertheless, theoretical and cosmological results call for its extension. A softly broken supersymmetric completion around the TeV scale solves several of the outstanding issues. Supersymmetry requires two Higgs doublets, leading to five physical Higgs states. READ MORE
