1. 1. Determining backgrounds with misidentified leptons in the ATLAS Higgs boson analysis

   Master-uppsats, KTH/Fysik

   Författare :Leo Qiyuan Hu; [2023]
   Nyckelord :Particle Physics; ATLAS detector; Fake Factor method; Higgs boson; lepton misreconstruction; misidentified events; Partikelfysik; ATLAS detektorn; Fake Factor-metoden; Higgs boson; lepton felrekonstruktion; felidentifierade händelser;

   Sammanfattning : This thesis presents an analysis of misidentified leptons in the Higgs boson decaychannel H → W W ∗ → lνlν. Misidentified leptons, resulting from jets misidentifiedas leptons, mimic the signal of a Higgs boson decay, resulting in a backgroundcontribution to the signal. LÄS MER

3. 2. Optimization of event selection and fake background estimation in a search for heavy scalars in dilepton final states with the ATLAS detector

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

   Författare :Marius Burman Ingeberg; [2021]
   Nyckelord :Physics; Particle physics; ATLAS; Standard Model; CERN; LHC; Higgs boson; Exotic Higgs Boson; Dilepton final states; Optimization; Physics and Astronomy;

   Sammanfattning : The discovery of the Higgs boson h in 2012 further confirmed the remarkable accuracy of the Standard Model (SM). Despite this, some compelling excesses in multi-lepton final states were recorded in both major runs of the Large Hadron Collider (LHC). LÄS MER
