  2. 21. Dark Matter in the Galactic Halo : A Search Using Neutrino Induced Cascades in the DeepCore Extension of IceCube

    Author : Henric Taavola; Olga Botner; Allan Hallgren; Carlos Perez de los Heros; Jodi Cooley; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dark matter; WIMP; neutralino; MSSM; neutrino telescope; IceCube; DeepCore; Galactic halo; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Abstract : A search for Weakly Interacting Massive Particles (WIMPs) annihilating in the dark matter halo of the Milky Way was performed, using data from the IceCube Neutrino Observatory and its low-energy extension DeepCore. The data were collected during one year between 2011 to 2012 corresponding to 329.1 days of detector livetime. READ MORE

  4. 22. Phenomenology of neutrino properties, unification, and Higgs couplings beyond the Standard Model

    Author : Stella Riad; Tommy Ohlsson; Nuria Rius; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Effective field theories; neutrino physics; extra dimensions; universal extra dimensions; Higgs physics; renormalization group running; Bayesian statistics; grand unified theories; Fysik; Physics;

    Abstract : The vast majority of experiments in particle physics can be described by the Standard Model of particle physics (SM). However, there are indications for physics beyond it. The only experimentally demonstrated problem of the model is the difficulty to describe neutrino masses and leptonic mixing. READ MORE

  5. 23. On the Search for High-Energy Neutrinos : Analysis of data from AMANDA-II

    Author : Johan Lundberg; Allan Hallgren; Olga Botner; Els de Wolf; Uppsala universitet; []
    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; Physics; 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

  6. 24. Search for Neutrinos from Gamma-ray Bursts using the IceCube Neutrino Observatory

    Author : Kunal Avinash Deoskar; Chad Finley; Klas Hultqvist; Paschal Coyle; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Gamma-ray bursts; neutrinos; IceCube Neutrino Observatory; Physics; fysik;

    Abstract : Gamma ray bursts (GRBs) are short bursts of high energy γ-radiation and are among some of the most energetic phenomena in the universe. GRBs have three distinct emission phases: the prompt phase with high-energy γ-rays, the precursor phase which is the time interval before the prompt phase and is reported to have an additional smaller burst for some GRBs, and the afterglow phase which is the time interval after the prompt phase with observations for electromagnetic radiation across a large wavelength range reported for many GRBs.
