1. 1. A search for Supersymmetry in final states with two same-flavor opposite-sign leptons, jets and missing transverse momentum with the ATLAS detector

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ATLAS; LHC; supersymmetry; Fysik; Physics;

   Sammanfattning : This thesis presents a search for Supersymmetry in final states containing two same-flavor opposite-sign leptons, jets and large missing transverse momentum. The search makes use of 36.1 fb−1 of proton-proton collision data collected at a center-of-mass energy of √s = 13 TeV by the ATLAS detector at the Large Hadron Collider. LÄS MER

3. 2. Haystacks and Needles : Measuring the number of proton collisions in ATLAS and probing them for the production of new exotic particles

   Sammanfattning : This thesis describes my work on the ATLAS luminosity measurement and on two searches for physics beyond the Standard Model, performed using √s = 13 TeV proton-proton (pp) collision data recorded by the ATLAS detector at CERN during Run 2 of the LHC in the years 2015-2018ATLAS employs several detectors and methods to measure the relative luminosity and the absolute scale is determined using van der Meer scans during dedicated low-luminosity running periods in each year. The thesis presents the details of the track-counting method which is used to extrapolate the calibration to the high-luminosity physics data-taking regime. LÄS MER
