1. Searches for supersymmetric long-lived particles with displaced-vertex signatures and studies of the electronic noise in the Tile Calorimeter at the ATLAS experiment
Sammanfattning : The Standard Model of particle physics is successful at describing nature on the smallest scales, but it has known flaws. These can be remedied by extended theories, such as supersymmetry. A quantum number in the supersymmetry framework is R-parity. This quantity is generally conserved, but can be violated. LÄS MER
2. Studies of the electronic noise of the Tile Calorimeter and the development of a material map for searches for exotic long-lived particles which decay
Sammanfattning : This thesis contains two major topics related to the ATLAS experiment: the calibration of electronic noise in the tile calorimeter and the development of a detailed map of the material in the inner tracker used in searches for long-lived particles.The noise in TileCal is shown to be consistent with the expectations based on heat and radiation.

3. Searches for Massive Highly Ionising Particles at the ATLAS Experiment and in Polar Volcanic Rocks, and Performance Studies of the First Level ATLAS Trigger System
Sammanfattning : The Standard Model (SM) of particle physics describes the elementary particles and their interactions. Despite passing a number of high precision falsification tests, it is argued that the SM suffers from a number of shortcomings. Many Beyond the Standard Model (BSM) theories have therefore been postulated. LÄS MER
4. Studies of triggering and exotic particle searches at ATLAS, and a search for trapped monopoles
Sammanfattning : The ATLAS detector at the LHC operated through 2011 and 2012 with 7 and 8 TeV centre-of-mass energy of its colliding proton bunches, respectively. One if its main objectives is to search for physics beyond the Standard Model. LÄS MER
5. Bright Needles in a Haystack : A Search for Magnetic Monopoles Using the IceCube Neutrino Observatory
Sammanfattning : The IceCube Neutrino Observatory at the geographic South Pole is designed to detect the light produced by the daughter-particles of in-ice neutrino-nucleon interactions, using one cubic kilometer of ice instrumented with more than 5000 optical sensors.Magnetic monopoles are hypothetical particles with non-zero magnetic charge, predicted to exist in many extensions of the Standard Model of particle physics.
