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. 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

3. A literature review of FASERν - An emulsion detector for collider neutrinos
University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionenAbstract : In 2021, the ForwArd Search ExpeRiment (FASER) will start searching for light and weakly coupled particles 480m from the proton-proton collision point of ATLAS at the Large Hadron Collider (LHC). The FASER main detector will have a sub-detector, FASERν, sensitive to high-energy collider neutrinos of all flavours. READ MORE

4. 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 institutionenAbstract : 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

5. Coordinate conversion for the Hough transform
University essay from Uppsala universitet/HögenergifysikAbstract : This thesis attempts to develop a conversion algorithm between local coordinates in constituent detector modules and global coordinates encompassing the whole detector structure in a generic detector. The thesis is a part of preparatory work for studying the Hough Transform as a means of track reconstruction in the level-1 hardware trigger in the upgraded trigger and data acquisition (TDAQ) system in the phase 2 upgrade of the ATLAS detector at CERN.
