1. Non-linear effects in the ATLAS track-counting luminosity measurement
University essay from Uppsala universitet/HögenergifysikAbstract : In this thesis the linearity of the ATLAS track-counting luminosity measurement is studied using two different sets Monte Carlo simulated crossings of proton-proton bunches. A primary high-momentum, or hard, interaction must be chosen for the Monte Carlo simulation. READ MORE

2. Laser Metrology for assembly of ATLAS ITk-Strips
University essay from Uppsala universitet/Institutionen för materialvetenskapAbstract : The ATLAS detector at CERN's Large Hadron Collider has been instrumental in scientific discoveries,including the Higgs particle. As part of the High Luminosity (HL) upgrade, the current Inner Detector (ID) isbeing replaced by the new IInner Tracker (ITk), and Uppsala University is collaborating with industrypartner NOTE to produce around 700 modules for the ITk.

3. Determining backgrounds with misidentified leptons in the ATLAS Higgs boson analysis
University essay from KTH/FysikAbstract : 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. READ MORE

4. ATLAS Inner Tracker Upgrade for HL-LHC: Silicon microstrip detector metrology
University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionenAbstract : The Large Hadron Collider (LHC) will be upgraded to the High-Luminosity LHC (HL-LHC) by the end of this decade, with five times larger luminosity and 200 inelastic collisions per proton-proton bunch crossing. Thus, the ATLAS detector is challenged to survive the stronger radiation and the increased particle flux. READ MORE

5. Constraining Physics Beyond the Standard Model with Emerging Jets using the ATLAS Experiment
University essay from KTH/FysikAbstract : Dark matter, the unknown matter that constitutes 85% of all matter in the universe, is one of the greatest mysteries in fundamental physics. One theory that might explain dark matter predicts that there are long-lived particles known as dark pions. READ MORE
