  1. 11. Searches for exotic stable massive particles with the ATLAS experiment

    Författare :Christian Ohm; David Milstead; Torbjörn Moa; Albert Roeck; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ATLAS; ATLAS experiment; supersymmetry; squark; gluino; stable massive particles; long-lived particles; physics analysis; search analysis; LHC; Large Hadron Collider; fysik; Physics;

    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. 12. Search for New Scalar Particles with ATLAS

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Large Hadron Collider; ATLAS; Standard Model; Higgs; supersymmetry; calorimeter; Physics; fysik;

    Sammanfattning : The Large Hadron Collider (LHC) is currently the most powerful particle accelerator ever built. It accelerates protons and collides them at the center of mass energy of √s = 13 TeV. LÄS MER

  3. 13. A Central Rapidity Straw Tracker and Measurements on Cryogenic Components for the Large Hadron Collider

    Författare :Hans Danielsson; Partikel- och kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; physical instrumentation; tracker; transsition radiation; LHC; cryogenics; superconducting; Metrology; helium; Metrologi; fysisk instrumentering; Fysicumarkivet A:1997:Danielsson; Fysicumarkivet A:1997:Danielsson;

    Sammanfattning : This thesis is divided into two parts in which two different aspects of the Large Hadron Collider (LHC) Project are discussed. The first part describes the design of a transition radiation tracker (TRT) for the inner detector in ATLAS. In particular, the barrel part was studied in detail. The barrel TRT consists of 52 544 1.
