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. Generalized Abelian Gauge Theory & Generalized Global Symmetry

   University essay from Uppsala universitet/Teoretisk fysik

   Author : Emil Hössjer; [2020]
   Keywords : Differential characters; Wilson lines; generalized global symmetry; BF theory; Maxwell theory; spontaneous symmetry breaking; intersection number; selection rules; Noether theorem; sphere bundle; t Hooft operator;

   Abstract : 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. READ MORE

5. 4. QFT and Spontaneous Symmetry Breaking

   University essay from Uppsala universitet/Teoretisk fysik

   Author : Sheila Chauwinoir; [2020]
   Keywords : quantum field theory; abelian and non-abelian gauge theories; quantum electrodynamics; quantum chromodynamics; electroweak interaction; spontaneous symmetry breaking; higgs mechanism;

   Abstract : 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.

6. 5. Construction of the Higgs Mechanism and the Lee-Quigg-Thacker-bound

   University essay from Uppsala universitet/Högenergifysik

   Author : Franz Wilhelm; [2019]
   Keywords : higgs mechanism; higgs; LQT; LQT-bound; spontaneous symmetry breaking; symmetry breaking; electroweak sector; higgs mass;

   Abstract : 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. READ MORE
