  1. 1. Phenomenology of Inert Scalar and Supersymmetric Dark Matter

    Författare :Erik Lundström; Joakim Edsjö; Lars Bergström; Michel Tytgat; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Dark matter; inert scalars; supersymmetry; indirect detection; accelerator searches; Physics; Fysik; Astroparticle physics; Astropartikelfysik; Elementary particle physics; Elementarpartikelfysik; teoretisk fysik; Theoretical Physics;

    Sammanfattning : While the dark matter has so far only revealed itself through the gravitational influence it exerts on its surroundings, there are good reasons to believe it is made up by WIMPs – a hypothetical class of heavy elementary particles not encompassed by the Standard Model of particle physics. The Inert Doublet Model constitutes a simple extension of the Standard Model Higgs sector. LÄS MER

  3. 2. Phenomenological Studies on Supersymmetry and the Strong Force

    Författare :Peter Skands; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; R-parity violation; Physics; beam remnants; hadronisation; parton showers; underlying event; Supersymmetry; Fysik; QCD; Fysicumarkivet A:2004:Skands;

    Sammanfattning : In this thesis, we first consider the phenomenology of R-parity violating supersymmetric extensions of the Standard Model. Specifically, a large number of Lepton and Baryon Number violating decays of sparticles to particles are implemented in the Pythia event generator. LÄS MER

  4. 3. Phenomenology of Higgs Bosons Beyond the Standard Model

    Författare :Glenn Wouda; Rikard Enberg; Gunnar Ingelman; Johan Rathsman; Rui Santos; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Particle physics; The Standard Model; Higgs bosons; Higgs mechanism; Beyond the Standard Model; Two Higgs Doublet Models; Charged Higgs boson; Higgs decays; Supersymmetry; Renormalization; LHC; Collider constraints; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Sammanfattning : After a long history of searches, a Higgs boson H was discovered by the ATLAS and the CMS experiments at the Large Hadron Collider (LHC) in 2012. Its properties fit well the ones predicted by the Standard Model (SM) of particle physics. However, the SM can not explain other established properties of Nature, such as the existence of Dark Matter. LÄS MER

  5. 4. 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

  7. 5. Strings, Gravitons, and Effective Field Theories

    Författare :Igor Buchberger; Marcus Berg; Joseph A. Minahan; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; string theory; amplitudes; supersymmetry; particle phenomenology; BMSSM; modified gravity; bimetric; massive gravity; Lie algebras; ribbon categories; Physics; Fysik;

    Sammanfattning : This thesis concerns a range of aspects of theoretical physics. It is composed of two parts. In the first part we motivate our line of research, and introduce and discuss the relevant concepts. In the second part, four research papers are collected. LÄS MER
