1. 1. Phase Transitions in the Two-Higgs-Doublet Model with a Softly-Broken Z2 Symmetry

   Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Författare :Filip Gustavsson; [2023]
   Nyckelord :Particle Physics; Beyond Standard Model; Two-Higgs Doublet Model; 2HDM; Electroweak Phase Transitions; Strong First-order Phase Transition; Dimensional Reduction; CP-conserving; Softly broken Z2-symmetry; Physics and Astronomy;

   Sammanfattning : The two-Higgs-doublet model (2HDM) is an extension to the Standard Model which adds a second Higgs doublet. This extension provides freedom within the model, in comparison to the Standard Model, which makes it possible to study strong electroweak phase transitions. LÄS MER

3. 2. Strongly First Order Phase Transitions and The Possibility of Electroweak Baryogenesis in General Two-Higgs-Doublet Models

   Master-uppsats, Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Författare :Nils Hermansson Truedsson; [2016]
   Nyckelord :Two-Higgs-Doublet Models; 2HDM; Electroweak Phase Transition; Baryon Asymmetry; Electroweak Baryogenesis; Beyond Standard Model; BSM; Theoretical Particle Physics; Physics and Astronomy;

   Sammanfattning : The possibility to have a strongly first order electroweak phase transition, which is one of the Sakharov conditions for electroweak baryogenesis together with $\mathcal{CP}$ violation and baryon number violation, in general Two-Higgs-Doublet Models (2HDMs) is here investigated. Different kinds of $\mathbb{Z}_{2}$ breaking beyond standard assumptions are studied, in particular by allowing it to be completely broken as well as by assuming it to be only approximately preserved in the Yukawa sector.
