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. Towards observing HH with ATLAS: ZH production and assessing theoretical uncertainties

   University essay from KTH/Fysik

   Author : Jonatan Gisslén; [2021]
   Keywords : ;

   Abstract : Even though the Standard Model of particle physics represents one of the triumphs of modern physics and seems to predict the outcome of any collision experiment, it has several shortcomings and therefore needs to be extended. After the discovery of the Higgs boson, one of the main aims of experimental particle physics is to probe the Standard Model for measurements that deviate from predictions, as this would imply new physics.

4. 3. Event Generators and Light Dark Matter

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Michal Nowak; [2019]
   Keywords : Event Generators; Dark Matter; Particle Kinematics; Particle Scattering; Physics and Astronomy;

   Abstract : Recently, a number of experiments have been proposed with the aim of finding light dark matter. In particular, the proposed LDMX experiment is meant to utilize electron scattering off metal nuclei to excite dark matter emissions. Motivated by this, we construct an event generator for electrons scattering off metal nuclei. READ MORE

5. 4. PARTON SHOWER UNCERTAINTIES ON THE TOP MASS

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Hristina Georgieva Hristova; [2019]
   Keywords : top quark mass; uncertainty; Lund Monte Carlo; Pythia; Physics and Astronomy;

   Abstract : The non-Abelian QCD nature allows for pp collisions to contain gluon emissions off quarks as well as gluon branchings into further gluons — a structure that can be described by the parton shower model. In this project we present the results of the impact the shower has on the reconstruction of the W-boson and top quark masses using Pythia, the Lund Monte Carlo event generator. READ MORE

6. 5. The space--time structure of hadron production in high-energy collisions

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

   Author : Silvia Ferreres; [2018]
   Keywords : event generator; space--time implementation; hadron production; hadron density; space--time; Physics and Astronomy;

   Abstract : In this thesis, the space--time picture of the hadronization model has been implemented in the event generator Pythia. From this implementation, the hadronic behaviour has been studied for different scenarios, in order to begin addressing the unexpected collective behaviour of high-multiplicity pp events, which is typical for heavy-ion collisions.
