1. Phase Transitions in the Two-Higgs-Doublet Model with a Softly-Broken Z2 Symmetry
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisationAbstract : 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. READ MORE

2. Electroweak Phase Transition in the Standard Model Effective Field Theory
University essay from Uppsala universitet/HögenergifysikAbstract : At least two Cosmological phase transitions are very probable to have happened since the beginning of the universe, one of them being the electroweak phase transition responsible for the breaking of the EW symmetry. It is possible that the EW phase transition could have caused the observed baryon asymmetry of the universe and therefore provide an explanation for the baryon asymmetry problem. READ MORE

3. Searching for signatures of compositeness of the Higgs boson
University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisationAbstract : In this master thesis we consider some phenomenological aspects of two-Higgs-doublet models, both elementary and composite ones. The emphasis is on calculating and understanding first order phase transitions in such models, constrained to be in agreement with existing collider data on the Higgs sector. READ MORE

4. Quartic Higgs self-coupling at a 100 TeV pp collider
University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisationAbstract : We present a parton-level phenomenological study of triple-Higgs production at leading order in proton-proton collisions at a center-of-mass energy of 100 TeV with an integrated luminosity of 30 ab^-1. This study aims to estimate the prospects for measuring the signal hhh production observable at the Future Circular Collider. READ MORE

5. No sign of a left-handedness in GeV photon arrival directions
University essay from Stockholms universitet/Institutionen för astronomiAbstract : A non-zero helicity of cosmological magnetic fields could, if detected, have important implications for models of the electroweak phase transition in the early Universe. It has been suggested that the helicity of such a field could be related to the handedness of photon arrival directions in the diffuse gamma-ray sky observed by the \emph{Fermi} Large Area Telescope (LAT).
