  2. 1. ATLAS Calorimetry : Hadronic Calibration Studies

    Author : Karl-Johan Grahn; Bengt Lund-Jensen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Abstract : 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. READ MORE

  4. 2. Immunological and virologica response to antiretroviral treatment (art) in patients infected with different HIV-1 genetic subtypes

    Author : Ann Atlas; Karolinska Institutet; Karolinska Institutet; []
    Keywords : HIV- 1 genetic subtype; CD4 T cell count; viral load; activation markers; IL-7;

    Abstract : 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. READ MORE

  5. 3. Luminosity determination and simulation of the LUCID detector at the ATLAS experiment

    Author : Jacob Groth-Jensen; Partikel- och kärnfysik; ATLAS Collaboration; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LHC; LUCID; Luminosity determination; Performance study; ATLAS; Gauge boson production; Fysicumarkivet A:2010:Groth-Jensen;

    Abstract : 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. READ MORE

  6. 4. Search for Weakly Produced Supersymmetric Particles in the ATLAS Experiment

    Author : Maja Tylmad; Christophe Clément; Barbro Åsman; Patrice Verdier; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ATLAS; ATLAS experiment; supersymmetry; chargino; neutralino; physics analysis; LHC; Large Hadron Collider; fysik; Physics;

    Abstract : 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. READ MORE

  7. 5. Search for beyond Standard Model physics with same-sign dileptons

    Author : Anthony Hawkins; Partikel- och kärnfysik; ATLAS Collaboration; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Doubly Charge Higgs; Beyond Standard Model; LHC; ATLAS; TRT; Same-sign leptons; Fysicumarkivet A:2014:Hawkins;

    Abstract : 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. READ MORE
