  1. 1. Top-Quark and Charged Higgs Boson Production at Hadron Colliders : Data Analysis at the DØ Experiment and Simulations for the ATLAS Detector

    Författare :Nils Gollub; Tord Ekelöf; Richard Brenner; Patrizia Azzi; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Elementary particle physics; ATLAS; LHC; charged Higgs boson; MSSM; D0; Tevatron; top quark; elementary particle physics; Elementarpartikelfysik; Elementary particle physics; Elementarpartikelfysik;

    Sammanfattning : This thesis treats two different projects, both aiming at experimental tests at hadron colliders of some specific predictions of the Standard Model (SM) of particle physics and of its Minimal Supersymmetric extension (MSSM). The thesis is based on four papers. LÄS MER

  3. 2. Neutrino Oscillations and Charged Higgs Bosons – Experimental Projects for Physics beyond the Standard Model

    Författare :Christian Hansen; Tord Ekelöf; Blair Ratcliff; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Elementary particle physics; CERN; LHC; ATLAS; charged; Higgs; SUSY; MSSM; oscillating; neutrino; RICH; CNGS; HPD; Elementarpartikelfysik; Elementary particle physics; Elementarpartikelfysik;

    Sammanfattning : This thesis is based on work done in two different experimental projects. The first project, the Tau RICH, is a previously proposed τ-neutrino appearance experiment for the CERN neutrino beam at the Gran Sasso laboratory in Italy. The proposed experimental concept is based on the use of focusing RICH detectors with liquid radiator (C6F14). LÄS MER

  5. 4. Charged Higgs Bosons at the ATLAS Experiment and Beyond

    Författare :Elias Coniavitis; Richard Brenner; Tord Ekelöf; Johan Rathsman; Marco Battaglia; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 5. A Search for Dark Matter in the Sun with AMANDA and IceCube

    Författare :Olle Engdegård; Olga Botner; Allan Hallgren; Jodi Cooley; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dark matter; WIMP; neutralino; MSSM; Kaluza-Klein; IceCube; AMANDA; neutrino telescope; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Sammanfattning : A search for weakly interacting massive particles (WIMPs) annihilating in the Sun was performed with the IceCube and AMANDA neutrino telescopes, using data from 2008 corresponding to 149 days of livetime. Assuming that particles in the dark matter halo scatter and accumulate in the centre of the Sun, Majorana WIMPs may pair-wise annihilate and give rise to a neutrino signal detectable in an experiment at Earth.
