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

    Detta är en avhandling från Hans Danielsson, div PPE, CERN, CH-1211 Geneva 23, Switzerland

    Författare :Hans Danielsson; Lunds universitet.; Lund University.; [1997]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; physical instrumentation; tracker; transsition radiation; LHC; cryogenics; superconducting; Metrology; helium; Metrologi; fysisk instrumentering; 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.

  2. 2. The search for a standard model Higgs at the LHC and electron identification using transition radiation in the ATLAS tracker

    Detta är en avhandling från Elementary Particle Physics, Lund University, Box 118, 221 00 Lund, Sweden

    Författare :Ulrik Egede; Lunds universitet.; Lund University.; [1997]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum field theory; Elementary particle physics; tracker; Large Hadron Collider; pion rejection; pattern recognition; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:1998:Egede;

    Sammanfattning : The Large Hadron Collider (LHC) will be ready for proton-proton collisions in the year 2005 and the ATLAS detector will be one of the two experiments at the LHC which will explore a new and higher energy range for particle physics. In this thesis, an analysis of the power of the ATLAS detector to detect a Standard Model Higgs boson has been performed. LÄS MER

  3. 3. B-physics potential of the ATLAS experiment and performance of the ATLAS Transition Radiation Tracker

    Detta är en avhandling från Lund University, Div. EHEP, Box.118, 22100-Lund.Sweden

    Författare :Chafik Driouichi; Lunds universitet.; Lund University.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ATLAS; B-physics; LHC; Bc meson; Elementary particle physics; Transition Radiation Tracker; quantum field theory; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:2004:Driouichi;

    Sammanfattning : The ATLAS experiment is one of the four experiments at the Large Hadron Collider (LHC), which is supposed to be operational in early 2007. Proton-proton collisions at an unprecedented center-of-mass energy of 14 TeV will probe new frontiers of the universe, hopefully providing a better understanding of the laws governing our universe.

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Beyond Standard Model; ATLAS; LHC; Fourth family of quarks; Same-sign top production; Drift tubes; TRT; QCD; Supersymmetry; Inner Detector calibration; Tracking;

    Sammanfattning : This thesis contains two different aspects of my research work towards physics in proton-proton collisions in the ATLAS experiment at the LHC. The first part is focused on the understanding and developing of a calibration system to obtain the best possible charged particle reconstruction in the Transition Radiation Tracker. LÄS MER

  5. 5. Charged Higgs Bosons at the ATLAS Experiment and Beyond

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Sammanfattning : In the ATLAS experiment at the Large Hadron Collider (LHC) at CERN, direct searches for the elusive Higgs boson will be conducted, as well as for physics beyond the Standard Model. The charged Higgs boson (H±) is interesting both as a part of the Higgs sector, and as a clear sign of new physics. LÄS MER
