  1. 1. Looking for the Charged Higgs Boson Simulation Studies for the ATLAS Experiment

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Martin Flechl; Uppsala universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; charged Higgs; tau; ATLAS; HEP; CERN; LHC; Particle Physics; Grid; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik; högenergifysik; High Energy Physics;

    Abstract : The discovery of a charged Higgs boson (H+) would be an unambiguous sign of physics beyond the Standard Model. This thesis describes preparations for the H+ search with the ATLAS experiment at the Large Hadron Collider at CERN. The H+ discovery potential is evaluated, and tools for H+ searches are developed and refined. READ MORE

  2. 2. Search for Weakly Produced Supersymmetric Particles in the ATLAS Experiment

    University dissertation from Stockholm : Department of Physics, Stockholm University

    Author : Maja Tylmad; Stockholms universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ATLAS; ATLAS experiment; supersymmetry; chargino; neutralino; physics analysis; LHC; Large Hadron Collider; Physics; fysik;

    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

  3. 3. Searches for exotic stable massive particles with the ATLAS experiment

    University dissertation from Stockholm : Department of Physics, Stockholm University

    Author : Christian Ohm; Stockholms universitet.; [2011]
    Keywords : 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;

    Abstract : 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 . READ MORE

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Elias Coniavitis; Uppsala universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; particle physics; Standard Model; beyond the Standard Model; supersymmetry; MSSM; Higgs physics; charged Higgs boson; LHC; ATLAS; ATLAS Semi-Conductor Tracker; SCT; tau lepton; Lorentz angle; CLIC; NATURAL SCIENCES Physics Elementary particle physics; NATURVETENSKAP Fysik Elementarpartikelfysik; High Energy Physics; Högenergifysik;

    Abstract : 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. READ MORE

  5. 5. Hunting the Charged Higgs Boson with Lepton Signatures in the ATLAS Experiment

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Alexander Madsen; Uppsala universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; charged Higgs boson; ATLAS; LHC; 2HDM; MSSM; particle physics; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Abstract : This thesis presents searches for a charged Higgs boson (H±) in proton-proton collisions with center-of-mass energies of 7 TeV and 8 TeV, using data collected by the ATLAS experiment at the Large Hadron Collider at CERN. Multiple search channels are used with the common characteristic of at least one charged lepton (electron or muon) that effectively reduces the multi-jet background and is used for efficient triggering.
