  2. 2. 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; Gunnar Ingelman; Johan Rathsman; Jonathan Ellis; [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

  3. 3. Experimental studies of particle production in ultra-relativistic heavy ion collisions

    University dissertation from Division of Cosmic and Subatomic Physics, Department of Physics, Lund University
