  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. Hotad av en tandlös tiger : En argumentationsanalys av debatterna om de polska domstolsreformerna i LIBE utskottet 2018-2020

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för statsvetenskap (ST)

    Författare :Jacob Nääf; [2020]
    Nyckelord :EU; LIBE-Utskottet; Polen; Argumentationsanalys; Artikel 7; Domstolsreformen; Normativ Makt; Neoklassisk realism;

    Sammanfattning : This study examines the debates that were held in the LIBE committee between 2018 - 2020 in relation to Polands judicial reforms. EU claims that the reforms are incompliant with the treaty of the european union but Poland have so far not backed down. LÄS MER

  4. 3. Principal Component Analyses of Final States in Relativistic Nuclear Collisions using PYTHIA/Angantyr

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

    Författare :Nicoline Krogh Hemme; [2020]
    Nyckelord :Relativistic Nuclear Collisions; Heavy-ion Collisions; Pythia; Angantyr; String Shoving; Colour Reconnection; Principal Component Analysis; Anisotropic Flow; Elliptic Flow; Event-by-event Fluctuations; Physics and Astronomy;

    Sammanfattning : We develop a program to perform a principal component analysis of flow fluctuations using simulations of nuclear collisions produced by the PYTHIA/Angantyr event generator. We consider both p+p and p+Pb collision events and study the leading and subleading modes of the second flow harmonic. LÄS MER

  5. 4. Nonequilibrium gauge field in Two Particle Irreducible real time formalism

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

    Författare :Rasmus Hansen; [2019]
    Nyckelord :Gauge field; non-equilibrium; quantum field theory; Physics and Astronomy;

    Sammanfattning : The purpose of this thesis is to study what effect a photon field has on the equations of motion and the decay of a charged scalar field in thermal equilibrium at finite temperature and outside of thermal equilibrium. To do this we calculate the two-particle irreducible effective action for the mean fields and propagators and derive their equations of motion. LÄS MER

  7. 5. Near detector simulation studies for CP violation discovery with ESSnuSB

    Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :In-Pyo Yeo; [2019]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The neutrino oscillation experiment ESSnuSB aims to measure the CP violation phase in the lepton sector with an intense neutrino beam produced at ESS. If the CP violation is discovered, then the matter-antimatter asymmetry of the Universe can be possibly explained. LÄS MER
