  1. 16. Explaining B-> D^(*) tau nu Decays with a Two Higgs Doublet Model using the Froggatt-Nielsen Framework

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Emil Andersson; [2017]
    Keywords : Two Higgs Doublet Model; 2HDM; Froggatt-Nielsen; Flavon; B-meson; Higgs; Beyond Standard Model; BSM; Theoretical Particle Physics; Physics and Astronomy;

    Abstract : In recent years, the BaBar, Belle and LHCb experiments have observed an excess of $B\to D^{(*)}\tau\nu$ decays compared to Standard Model predictions. In this thesis, we investigate if it is possible to explain this excess with a two Higgs doublet model using the Froggatt-Nielsen framework. READ MORE

  3. 17. Kitaev models for topologically ordered phases of matter

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik

    Author : Eilind Karlsson; [2017]
    Keywords : ;

    Abstract : Condensed matter physics is the study of the macroscopic and microscopic properties of condensed phases of matter. For quite some time, Landau’s symmetry breaking theory was believed to describe and explain the nature of any phase transition. READ MORE

  4. 18. Abelian gauge symmetries in the two-Higgs-doublet model

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Franz Teichmann; [2017]
    Keywords : Physics and Astronomy;

    Abstract : The two-Higgs-doublet model is a promising extension of the Standard Model of particle physics, but it contains a large number of free parameters. With the intention to constrain this freedom, the model has been studied under different symmetries. In particular, a full classification of Abelian global symmetries has been presented in 2011.

  5. 19. Symmetrin i rörelsemönstret hos unga travhästar under inkörning och tidig träning

    University essay from SLU/Dept. of Anatomy, Physiology and Biochemistry

    Author : Mari Mykkeltvedt; [2017]
    Keywords : Locomotion symmetry; Lameness Locator; Standardbred yearlings;

    Abstract : Locomotion in young trotters during breaking and their first training period. A pilot study on four one-year-old trotter’s locomotion during breaking and their first training period. Studies have shown that horses that initiate training at early age have better chances to a successful racing carrier with less health problems. READ MORE

  6. 20. An Investigation of the Trinification Scalar Sector at One Loop

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Laurie Walk; [2017]
    Keywords : GUT; Trinification; Spontaneous Symmetry Breaking; Effective Field Theory; Effective Potential; Physics and Astronomy;

    Abstract : Throughout this work we investigate a trinification-based grand unification theory (GUT) with a global family symmetry, as a radiative origin of the Standard Model (SM). We show that after spontaneous symmetry breaking of the trinification gauge group, we can in theory construct an effective left-right symmetric model (LRSM) which breaks to the SM gauge group through radiative breaking induced by the running of the model’s parameters.
