  1. 1. Search for Higgs-like bosons through optimization of top-quark modelling

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Rafael Antonio Lopez; [2021]
    Keywords : ttbar; top quark modelling; BSM; 2HDM S; Higgs-like bosons; ATLAS; HWW; XSh; top estimation; top remodelling; Physics and Astronomy;

    Abstract : Accurate estimations of background processes associated with top-quarks are vital to studies concerned with finding new physics at the Large Hadron Collider (LHC)at CERN. Search for Higgs-like bosons in the ATLAS experiment at LHC was performed by optimising the use of b-jet tagging algorithms and improving on tt backgroundmodelling. READ MORE

  3. 2. Study of Kinematic Variables in Multi-Lepton Final States in search for an Exotic Higgs Boson

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Axel Gallén; [2021]
    Keywords : LHC; ATLAS; CERN; Standard Model; Higgs boson; Exotic Higgs boson; Kinematic variables; Physics and Astronomy;

    Abstract : The Large Hadron Collider in Geneva was constructed as a discovery machine. So far, the Higgs boson has been the only discovery at the Large Hadron Collider, but physicists keep on pushing the limit in order to discover new particles. READ MORE

  4. 3. Strongly First Order Phase Transitions and The Possibility of Electroweak Baryogenesis in General Two-Higgs-Doublet Models

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

    Author : Nils Hermansson Truedsson; [2016]
    Keywords : Two-Higgs-Doublet Models; 2HDM; Electroweak Phase Transition; Baryon Asymmetry; Electroweak Baryogenesis; Beyond Standard Model; BSM; Theoretical Particle Physics; Physics and Astronomy;

    Abstract : The possibility to have a strongly first order electroweak phase transition, which is one of the Sakharov conditions for electroweak baryogenesis together with $\mathcal{CP}$ violation and baryon number violation, in general Two-Higgs-Doublet Models (2HDMs) is here investigated. Different kinds of $\mathbb{Z}_{2}$ breaking beyond standard assumptions are studied, in particular by allowing it to be completely broken as well as by assuming it to be only approximately preserved in the Yukawa sector.
