  1. 1. Exploring electroweak symmetry breaking in the scale-invariant Two-Higgs-Doublet Model

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Erik Rustas; [2023]
    Keywords : Two-Higgs-Doublet Models; 2HDM; Scale-invariance; Baryogenesis; BSM; Baryon Asymmetry; Coleman-Weinberg Potential; Theoretical Particle Physics; Physics and Astronomy;

    Abstract : This thesis investigates the properties of a general scale-invariant Two-Higgs-Doublet Model and its phenomenological consequences with focus on the scalar sector. The concept suggests that introducing more CP-violation, both spontaneous and explicit, may make it possible to meet the Sakharov conditions and account for the Universe's baryon asymmetry.

  3. 2. Phenomenological exploration of flavored Grand Unification through high-scale matching and renormalization group flow

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Hector Tiblom; [2023]
    Keywords : Grand Unification; GUT; trinification; spontaneous symmetry breaking; effective field theory; EFT; high-scale matching; renormalization group flow; Physics and Astronomy;

    Abstract : The phenomenological success of the Standard Model (SM), and its unification of the electromagnetic and weak forces has inspired the search for a Grand Unified Theory (GUT), that dynamically reduces to the SM at low energies. In this work, we consider one such GUT, based on the trinification model [SU(3)]³ with an additional local SU(2) family symmetry, that is then broken directly to the gauge symmetry group of the SM.

  4. 3. Holographic RG-flows and the Domain-Wall/Cosmology correspondence

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Jean-François Vaduret; [2022]
    Keywords : holography; cosmology; domain-wall; AdS; CFT; correspondence;

    Abstract : In this master thesis we investigate implications of the Domain-Wall/Cosmology (DW/C) correspondence on one-point functions of holographic RG-flows. The thesis gives a detailed computation of linearized gauge-invariant Einstein equations in (d+1) dimensions while making the DW/C correspondence explicit. READ MORE

  5. 4. Strain-induced nonlinear Hall effect in graphene systems

    University essay from Stockholms universitet/Fysikum

    Author : Pedram Pakmehr; [2022]
    Keywords : ;

    Abstract : This thesis aims to study the nonlinear electrical transport response of monolayer and bilayer graphene systems under the influence of different lattice deformations (strain). Broken inversion and rotation symmetries can generate a second-order transverse current response called the nonlinear Hall effect in the presence of time-reversal symmetry. READ MORE

  6. 5. Domain wall solutions in the AdS/CFT correspondence

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Eduardo Mateos González; [2020]
    Keywords : AdS CFT correspondence; BW QFT correspondence;

    Abstract : In this thesis we study a particular realization of the Domain wall/Quantum Field Theory correspondence, a modification of the Anti de-Sitter/Conformal Field Theory correspondence that is used to study deformations of a Conformal Field Theory. In theQuantum gravity side of the duality we analyze a N = 1 gauged supergravity theory in 7 dimensions which presents two different Anti de-Sitter vacua, one of which preserves the full supersymmetry and one that breaks half of the supercharges.
