  1. 11. B-physics potential of the ATLAS experiment and performance of the ATLAS Transition Radiation Tracker

    Författare :Chafik Driouichi; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ATLAS; B-physics; LHC; Bc meson; Elementary particle physics; Transition Radiation Tracker; quantum field theory; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:2004:Driouichi;

    Sammanfattning : The ATLAS experiment is one of the four experiments at the Large Hadron Collider (LHC), which is supposed to be operational in early 2007. Proton-proton collisions at an unprecedented center-of-mass energy of 14 TeV will probe new frontiers of the universe, hopefully providing a better understanding of the laws governing our universe.

  3. 12. The search for a standard model Higgs at the LHC and electron identification using transition radiation in the ATLAS tracker

    Författare :Ulrik Egede; Partikel- och kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum field theory; Elementary particle physics; tracker; Large Hadron Collider; pion rejection; pattern recognition; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:1998:Egede;

    Sammanfattning : The Large Hadron Collider (LHC) will be ready for proton-proton collisions in the year 2005 and the ATLAS detector will be one of the two experiments at the LHC which will explore a new and higher energy range for particle physics. In this thesis, an analysis of the power of the ATLAS detector to detect a Standard Model Higgs boson has been performed. LÄS MER

  4. 13. A Dark Matter Search with AMANDA : Limits on the Muon Flux from Neutralino Annihilations at the Centre of the Earth with 1997-99 Data

    Författare :Patrik Ekström; Per Olof Hulth; Lee Thompson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Elementary particle physics; Elementarpartikelfysik;

    Sammanfattning : The nature of the dark matter in the Universe is one of the greatest mysteries in modern astronomy. The neutralino is a nonbaryonic dark matter candidate in minimal supersymmetric extensions to the standard model of particle physics. LÄS MER

  5. 14. Emittance preservation and luminosity tuning in future linear colliders

    Författare :Peder Eliasson; Tord Ekelöf; Grahame Blair; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; linear colliders; CLIC; ILC; emittance preservation; luminosity tuning; beam-based alignment; dispersion free steering; tuning bumps; trajectory feedback; static imperfections; dynamic imperfections; jitter; ground motion; ATL model; multi-pulse emittance; curved tunnel; Elementary particle physics; Elementarpartikelfysik;

    Sammanfattning : The future International Linear Collider (ILC) and Compact Linear Collider (CLIC) are intended for precision measurements of phenomena discovered at the Large Hadron Collider (LHC) and also for the discovery of new physics. In order to offer optimal conditions for such experiments, the new colliders must produce very-high-luminosity collisions at energies in the TeV regime. LÄS MER

  7. 15. Phenomenology of Charged Higgs Bosons and B-meson Decays

    Författare :David Eriksson; Johan Rathsman; Gunnar Ingelman; Fabio Maltoni; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Supersymmetry; Beyond Standard Model; B-Physics; Charged Higgs Boson; LHC; QCD; Spin Correlations; CMSSM; NUHM; Elementary particle physics; Elementarpartikelfysik;

    Sammanfattning : For more than 30 years the Standard Model has been the theoretical foundation for particle physics. The theory has been verified successfully by experimental tests. Its biggest shortcoming is the non-discovery of the Higgs boson,responsible for giving the other particles masses. LÄS MER
