1. ATLAS Calorimetry : Hadronic Calibration Studies
Sammanfattning : The ATLAS experiment -- situated at the Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN) in Geneva -- is on schedule to take its first collision data in 2009. Physics topics include finding the Higgs boson, heavy quark physics, and looking for extensions of the standard model such as supersymmetry. LÄS MER
2. Immunological and virologica response to antiretroviral treatment (art) in patients infected with different HIV-1 genetic subtypes
Sammanfattning : Genetic analyses of different strains of HIV- 1 have shown that isolates can be subdivided into groups, subtypes and circulating recombinant forms. Nine different genetic HIV-1 subtypes have been identified so far, named as A, B, C, D, F, G, H, J and K. LÄS MER
3. Luminosity determination and simulation of the LUCID detector at the ATLAS experiment
Sammanfattning : The aim of this thesis is to describe how the luminosity can be measured in the ATLAS experiment at the Large Hadron Collider. Luminosity is a fundamental quantity that is used in most physics studies at the LHC. For example in order to measure cross sections. LÄS MER
4. Search for Weakly Produced Supersymmetric Particles in the ATLAS Experiment
Sammanfattning : The Large Hadron Collider located at CERN is currently the most powerful particle accelerator and ATLAS is an experiment designed to exploit the high energy proton-proton collisions provided by the LHC. It opens a unique window to search for new physics at very high energy, such as supersymmetry, a postulated symmetry between fermions and bosons. LÄS MER
5. Search for beyond Standard Model physics with same-sign dileptons
Sammanfattning : An introduction into the theory and experimental background of particle physics and the ATLAS detector is given. The transition radiation tracker (TRT) which is vital to the particle tracking and identification is then described giving particular creedence to the calibration. The automation of this calibration is explained. LÄS MER
