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

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

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

   Abstract : 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.

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

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Nicoline Krogh Hemme; [2020]
   Keywords : 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;

   Abstract : 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. READ MORE

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

   University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

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

   Abstract : 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. READ MORE

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

   University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

   Author : In-Pyo Yeo; [2019]
   Keywords : Physics and Astronomy;

   Abstract : 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. READ MORE

6. 5. Performance of jet subtraction in pPb and PbPb collisions, without collectivity

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

   Author : Sebastian Grabowski; [2018]
   Keywords : heavy ion: scattering; Angantyr; underlying event; subtraction; jet: quenching; non-collectivity; stacking; jet: correlation; non-colliective; background; Physics and Astronomy;

   Abstract : We investigated the performance of basic jet subtraction, by the utilization of jet reconstruction generally used at the Large Hadron Collider (LHC). This was done by studying Z-bosons, in the dielectron decay channel, and the associated jet correlation in pp, pPb and PbPb collisions, using datasets generated by the Monte Carlo generator PYTHIA8.
