  2. 11. Dark Matter, Ancient Rocks, a Band of Higgs Bosons, and a Big Collider : or, Models of New Physics and Some Ways to Probe Them

    Author : Sebastian Baum; Katherine Freese; Marco Cirelli; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; particle phenomenology; supersymmetry; dark matter; higgs boson; teoretisk fysik; Theoretical Physics;

    Abstract : The past ~ 50 years have seen a remarkable success of particle physics. In the 1970s, the Standard Model was formulated and in 2012 its final ingredient, the Higgs boson, was discovered at the Large Hadron Collider (LHC). The Standard Model describes virtually all particle physics observable in the laboratory. READ MORE

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

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

    Abstract : 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). READ MORE

  5. 13. Search for a Neutral Higgs Boson with DELPHI

    Author : Tord G.M. Malmgren; James Pilcher; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Abstract : The mass of the neutral Higgs boson cannot be predicted by the Standard Model. Therefore, the particle is scanned for at different assumed masses. The search described here was done using data taken with the DELPHI detector during 1993-1994 (Ecm=91 GeV), 1996 (Ecm=161 and 172 GeV) and during 1997 (Ecm=183 GeV). READ MORE

  6. 14. Searching for a charged Higgs boson and development of a hardware track trigger with the ATLAS experiment

    Author : Joakim Gradin; Elin Bergeås Kuutmann; Johann Collot; Richard Brenner; Susan Shotkin-Gascon; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; High energy physics; charged Higgs boson; Particle tracking; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Abstract : This thesis describes searches for a heavy charged Higgs boson decaying into a top and bottom quark pair, and the development of a hardware track trigger with theATLAS experiment. The data for the two searches was collected with the ATLAS detector at the Large Hadron Collider(LHC) with pp collision energies of √s = 8 and 13 TeV, and corresponds to an integrated luminosity of 20.
