  1. 1. Exploring electroweak symmetry breaking in the scale-invariant Two-Higgs-Doublet Model

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

    Författare :Erik Rustas; [2023]
    Nyckelord :Two-Higgs-Doublet Models; 2HDM; Scale-invariance; Baryogenesis; BSM; Baryon Asymmetry; Coleman-Weinberg Potential; Theoretical Particle Physics; Physics and Astronomy;

    Sammanfattning : 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

  3. 2. Extending the Standard Model by a Dark and Visible Scalar Singlet

    Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Aram Fatah; [2020]
    Nyckelord :The two real singlet model; higgs boson; dark matter; beyond the standard model; bsm; scalar; Physics and Astronomy;

    Sammanfattning : In this thesis, we extend the Higgs sector of the Standard Model by two scalar singlets and impose a discrete Z2 symmetry on each of them, under which, both singlets are odd. One of the two scalar singlets will acquire a vacuum expectation value while the other one does not. LÄS MER

  4. 3. Omega Baryon Production as a Function of Multiplicity in Proton-Proton Collisions at $\sqrt{s}=13$ TeV

    Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Lisa Vergara Urrutia; [2019]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : In this thesis the production of the $\Omega^-$ and $\Omega^+$ baryons, in proton-proton collisions at $\sqrt{s}=13$ TeV, is analyzed as a function of charged-particle multiplicity. The events analyzed were recorded by the ALICE detector, at the LHC. LÄS MER

  5. 4. The first supernovae and the mass distribution of Population III stars

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Martin Mikitas; [2018]
    Nyckelord :Astronomy; Supernovae; STARFIT; Salpeter; IMF; Physics and Astronomy;

    Sammanfattning : The properties of the early Milky Way are quite mysterious and some are completely unknown even today. This study is the first one ever to analyze the mass distribution of Population III bulge stars. LÄS MER

  7. 5. Korruption - En jämförande studie över tid utifrån Sveriges och Islands situationer.

    L2-uppsats, Lunds universitet/Statsvetenskapliga institutionen

    Författare :Catharina Buhrgard; Tim Linder; [2018]
    Nyckelord :Sverige; Island; korruption; rättsväsende; jämförande studie; Law and Political Science;

    Sammanfattning : Denna uppsats studerar genom en jämförande studie korruption utifrån fallen Sverige och Island under tidsperioden 2002 till 2017. Varje stats rättsväsendes - för studien relevanta - lagförändringar jämförs med aspirationen att finna korruptionshämmande effekter inom dessa. LÄS MER
