  2. 16. The effect of surface steps and oxides on the catalytic activity on model Pd and Rh catalysts

    Author : Chu Zhang; Synkrotronljusfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Surface X-ray diffraction SXRD ; X-ray photonelectron spectroscopy; Catalytic activity; Oxide; Single Crystal surface; surface structure; vicinal surface; CO oxidation; stepped surface; Fysicumarkivet A:2018:Zhang;

    Abstract : A catalyst is a substance that can speed up the rate of a chemical reaction without itself being consumed. Catalysts are crucial for chemical production industries, where about 90% of all chemicals are produced using catalysts. READ MORE

  4. 17. Calibration of b-tagging efficiency and search for Dark Matter production in association with heavy flavour quarks with the ATLAS experiment

    Author : Anna Shcherbakova; Sara Strandberg; Chad Finley; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ATLAS; b-tagging; calibration; Dark Matter; simplified model; Physics; fysik; High Energy Physics;

    Abstract : The Large Hadron Collider (LHC) is the most powerful and complex particle accelerator ever built. The ATLAS detector is a general-purpose particle detector at the LHC, designed to cover a wide range of physics measurements. READ MORE

  5. 18. Top Quark Pair Production in ATLAS

    Author : Karl Gellerstedt; Jörgen Sjölin; Kerstin Jon-And; Cecilia Gerber; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; particle physics; top quark; LHC; ATLAS; fysik; Physics;

    Abstract : The Large Hadron Collider (LHC) at the international particle physics laboratory CERN in Switzerland is currently the most powerful particle accelerator on earth. This thesis presents analyses of proton-proton collisions at the energy √s = 7 TeV, recorded by ATLAS, one of the detectors at the LHC. READ MORE

  6. 19. Calibration of b-tagging and search for Dark Matter : Calibration of b-tagging efficiency and search for Dark Matter production in association with heavy flavour quarks with the ATLAS experiment

    Abstract : The Large Hadron Collider (LHC) is the most powerful and complex particle accelerator ever built. The ATLAS and the CMS are the two multipurpose particle detectors at the LHC, designed to cover a wide range of physics measurements. READ MORE

  7. 20. 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
