1. Exploring electroweak symmetry breaking in the scale-invariant Two-Higgs-Doublet Model
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisationSammanfattning : 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. LÄS MER
2. Phenomenological exploration of flavored Grand Unification through high-scale matching and renormalization group flow
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisationSammanfattning : 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.

3. Generalized Abelian Gauge Theory & Generalized Global Symmetry
Master-uppsats, Uppsala universitet/Teoretisk fysikSammanfattning : We study Cheeger-Simons differential characters in order to define higher form U(1) gauge fields and their Wilson lines. We then go on to define generalized global symmetries. This is a topological formulation of symmetries which has interesting consequences when the charged operators extend through space. LÄS MER
4. QFT and Spontaneous Symmetry Breaking
Kandidat-uppsats, Uppsala universitet/Teoretisk fysikSammanfattning : The aim of this project is to understand the structure of the Standard Model of the particle physics. Therefore quantum field theories (QFT) are studied in the both cases of abelian and non-abelian gauge theories i.e. quantum electrodynamics (QED), quantum chromodynamics (QCD) and electroweak interaction are reviewed.

5. Construction of the Higgs Mechanism and the Lee-Quigg-Thacker-bound
Kandidat-uppsats, Uppsala universitet/HögenergifysikSammanfattning : In this paper the higgs mechanism for the standard model is constructed in steps. First by considering spontaneous breaking of discrete and continuous global gauge invariance. Then spontaneous breaking of local gauge invariance. LÄS MER
