  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. The Effect of Temperature Gradients During Intercritical Annealing of Advanced High Strength Steels : Method Development for Experimental Streamlining

    Master-uppsats, KTH/Materialvetenskap

    Författare :Helena Ek Jendrny; [2023]
    Nyckelord :AHSS; Gleeble; Intercritical annealing; Retained austenite; Medium Mn Steel; AHSS; Gleeble; interkritisk glödgning; austenit; Medium Mn stål;

    Sammanfattning : The third-generation advanced high strength steels, AHSS, represent an opportunity for today’s steel development, where lighter materials with maintained strength and toughness are in demand. The unique properties of these materials often stem from a tailored microstructure. LÄS MER

  4. 3. Investigation of the mean photon energy in Kompaneets spectra

    Master-uppsats, KTH/Fysik

    Författare :Richárd Bagi; [2023]
    Nyckelord :Astroparticle Physics; Kompaneets equation; Astropartikelfysik; Kompaneetsekvationen;

    Sammanfattning : The Kompaneets equation describes the spectrum formation when hot fermions are injected into an opaque fermion-photon plasma in thermal equilibrium and inverse Compton-scatterings occur. The equation has three free parameters, the initial plasma thermal energy θ_u, the final plasmathermal energy θ_r and the average photon energy gain y_r. LÄS MER

  5. 4. Intercomparison of a Dynamic Ocean for Earth-like Aqua-planets

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Fredrik Plane; [2022]
    Nyckelord :Astrobiology; Planets; Aqua-planets; Atmosphere and Ocean physics; Exoplanet; Habitability; General Circulation Model; GCM; Climate Modelling; Dynamic Ocean;

    Sammanfattning : I present herein an ensemble of ROCKE-3D aqua-planet simulations which I compare with the simulations presented in the work of Yang et al. (2019) and other similar works. The focus was on contrasting differences in the greenhouse effect between the models. LÄS MER

  7. 5. Can Feebly Interacting Massive Particles (FIMP) constitute Dark Matter?

    Master-uppsats, KTH/Fysik

    Författare :Grandharva Appagere; [2021]
    Nyckelord :Dark Matter; Higgs¬portal; Freeze¬-in mechanism; FIMP; C-W Mechanism; Mörk materia; Higgsportal; frys-in-mekanism; FIMP; C-W mekanism;

    Sammanfattning : In this study, we investigate the feasibility of Feebly Interacting Massive particles (FIMP) as possible candidates to constitute the observed Dark Matter abundance in the universe. FIMPs are particles that couple very feebly with known particles in the Standard Model (SM). LÄS MER
