  2. 1. Charged Higgs Bosons at the ATLAS Experiment and Beyond

    Author : Elias Coniavitis; Richard Brenner; Tord Ekelöf; Johan Rathsman; Marco Battaglia; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; particle physics; Standard Model; beyond the Standard Model; supersymmetry; MSSM; Higgs physics; charged Higgs boson; LHC; ATLAS; ATLAS Semi-Conductor Tracker; SCT; tau lepton; Lorentz angle; CLIC; Elementary particle physics; Elementarpartikelfysik; High Energy Physics; Högenergifysik;

    Abstract : In the ATLAS experiment at the Large Hadron Collider (LHC) at CERN, direct searches for the elusive Higgs boson will be conducted, as well as for physics beyond the Standard Model. The charged Higgs boson (H±) is interesting both as a part of the Higgs sector, and as a clear sign of new physics. READ MORE

  4. 2. 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

  5. 3. The Powers of Perturbation Theory : Loops and Gauge Invariance in Particle Physics

    Author : Johan Löfgren; Rikard Enberg; Kimmo Kainulainen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Beyond the Standard Model; Electroweak phase transition; Perturbation theory; High Energy Physics; Högenergifysik;

    Abstract : The Standard Model is the best particle physics theory we have, but there are still phenomena that it cannot explain. In this thesis I have worked on two different projects that connect to two of the biggest unsolved questions of the Standard Model. READ MORE

  6. 4. Emittance and Energy Diagnostics for Electron Beams with Large Momentum Spread

    Author : Maja Olvegård; Volker Ziemann; Kay Wittenburg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; beam instrumentation; particle beam diagnostic; emittance; particle collider; particle accelerator; High Energy Physics; Högenergifysik;

    Abstract : Following the discovery of the Higgs-like boson at the Large Hadron Collider, there is demand for precision measurements on recent findings. The Compact Linear Collider, CLIC, is a candidate for a future linear electron-positron collider for such precision measurements. READ MORE

  7. 5. The Extremes of Neutrino Astronomy : From Fermi Bubbles with IceCube to Ice Studies with ARIANNA

    Author : Elisabeth Unger; Allan Hallgren; Olga Botner; Antonio Capone; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; astroparticle physics; neutrino telescopes; IceCube; Fermi bubbles; ARIANNA; horizontal propagation; surface wave propagation; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics; High Energy Physics; Högenergifysik;

    Abstract : The Fermi bubbles are extended regions of hard gamma-ray emission which were discovered with Fermi-LAT data to exist above and below the Galactic Center. In order to explain the origin of the gamma-rays, different theories are proposed. READ MORE
