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. Studying Elliptic Flow in High Centrality Pb-Pb Collisions using Proton Collision Background Fitting

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

   Författare :Philip Fredholm; [2023]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : In this report, the elliptic flow in high centrality Pb-Pb collisions is calculated using two particle correlations $v_2\{2\}$ but without any imposed separation in η with data taken from the ALICE experiment at CERN in 2015. Instead, measurements of the same correlations in proton-proton collisions is used as a background to account for non-flow effects and data is correlated between the time projection chamber and the forward multiplicity detectors in order to avoid intra-jet correlations.

4. 3. Matter-streams as sources of the Kerr metric

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

   Författare :Julian Boy; [2022]
   Nyckelord :General Relativity; Black holes; Physics; Kerr metric; Physics and Astronomy;

   Sammanfattning : An introduction to the thin-shell formalism and distributional approach to General Relativity is provided. The formalism is utilized to investigate possible distributions of matter that can act as a source to the Kerr metric. LÄS MER

5. 4. The impact of initial state radiation on jets from PbPb collisions

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

   Författare :Hilmi Kycyku; [2021]
   Nyckelord :heavy-ion physics; QGP; quark-gluon plasma; kvark-gluon plasma; initial state radiation; jets; medium response; Physics and Astronomy;

   Sammanfattning : This thesis presents the study of how initial state radiation impacts jets produced in pp and PbPb collisions, by investigating the transverse momentum spectra, the rapidity spectra and the differential jet shape. This is done for central collisions with nucleon-nucleom COM energy 2.76 TeV and 5.02 TeV. LÄS MER

7. 5. 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
