1. Searches for exotic stable massive particles with the ATLAS experiment
Sammanfattning : This thesis presents two signature-based searches for exotic long-lived particles using experimental data collected by the ATLAS experiment at the Large Hadron Collider (LHC) at CERN. At the LHC, proton-proton collisions take place at the world-record center-of-mass energy of 7 TeV and luminosities of up to 3×1033 cm-2s-1 . LÄS MER
2. Studies of Long-Lived Supersymmetric Top Quarks and Online Monitoring of the ATLAS First Level Calorimeter Trigger
Sammanfattning : The Large Hadron Collider (LHC) has recently started colliding protons at 7 TeV centre-of mass energy. Extensive searches for hitherto unobserved particles and physics processes will be made as part of an ambitious scientific programme which aims to answer some of the fundamental questions in modern physics.

3. A Search for Solar Neutralino Dark Matter with the AMANDA-II Neutrino Telescope
Sammanfattning : A relic density of Weakly Interacting Massive Particles (WIMPs) remaining from the Big Bang constitutes a promising solution to the Dark Matter problem. It is possible for such WIMPs to be trapped by and accumulate in gravitational potentials of massive dense objects such as the Sun. LÄS MER
4. Chip-based magnetic levitation of superconducting microparticles
Sammanfattning : Magnetically levitated superconductors are extremely isolated from the environment, their mechanical properties can be tuned magnetically, and can be coupled to quantum systems such as superconducting quantum circuits. As such, they are a promising experimental platform for the creation of massive spatial quantum states that would test quantum mechanics in a hitherto unexplored parameter regime. LÄS MER
5. Search for Gamma-ray Lines from Dark Matter with the Fermi Large Area Telescope
Sammanfattning : Dark matter (DM) constitutes one of the most intriguing but so far unresolved issues in physics. In many extensions of the Standard Model of particle physics, the existence of a stable Weakly Interacting Massive Particle (WIMP) is predicted. The WIMP is an excellent DM particle candidate.
