1. 1. Cosmological implications of a QCD-like composite Higgs model

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

   Author : Hristina Georgieva Hristova; [2021]
   Keywords : composite Higgs; technicolor; gravitational waves; LISA; phase transition; Physics and Astronomy;

   Abstract : Some of the shortcomings of the Standard Model of particle physics are the 'unnatural' value of the mass of the Higgs boson and the fact that the model cannot account for the process of baryogenesis - a mechanism which generates the observed asymmetry between matter and anti-matter in the Universe. The former is related to the fundamental scalar nature of the Higgs boson, connected to quadratic divergences in the mass corrections. READ MORE

3. 2. 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
