    • Analysis of 3D Pixel Detectors for the ATLAS Inner Tracker Upgrade 

      Heggelund, Andreas Løkken (The University of Bergen, 2017-06-16)
      The silicon 3D pixel detector represent a detector technology that has a higher radiation tolerance compared to the conventional planar pixel detectors. This detector technology is one of the technologies proposed to be ...

    • Charged-particle multiplicities in $pp$ interactions at $\sqrt{s}$ = 900 GeV measured with the ATLAS detector at the LHC 

      Aad, Georges; Buanes, Trygve; Burgess, Thomas; Eigen, Gerald; Johansen, Lars Gimmestad; Kastanas, Alex; Lipniacka, Anna; Mohn, Bjarte Alsaker; Øye, Ola Kristoffer; Sandaker, Heidi; Sjursen, Therese; Stugu, Bjarne; Tonoyan, Arshak; Ugland, Maren; Zutshi, V. (Elsevier, 2010-04)
      The first measurements from proton-proton collisions recorded with the ATLAS detector at the LHC are presented. Data were collected in December 2009 using a minimum-bias trigger during collisions at a centre-of-mass energy ...

    • Dark Matter Searches with ATLAS and Fermi 

      Morå, Knut Dundas (The University of Bergen, 2013-06-03)
      This thesis presents Dark matter inspired searches for supersymmetry with a one-tau analysis at ATLAS, which excludes a region close to that of allowed dark matter densities at m_0 ~ 400 GeV, m_1/2 ~ 600 GeV, tan \beta = ...

    • The Higgs Boson in Less Constrained Supersymmetric Models 

      Pettersen, Helge Egil Seime (The University of Bergen, 2012-06-01)
      In this thesis, we explore the phenomenological minimal supersymmetric standard model (pMSSM) in the context of the Higgs boson. If the emerging results from the LHC are real, will the pMSSM be able to accommodate this? ...

    • Measurement of the top-quark mass in the fully hadronic decay channel from ATLAS data at $\sqrt{s}=7$ TeV 

      Aad, Georges; Abbott, Brad; Abdallah, Jalal; Abdel Khalek, Samah; Abdinov, Ovsat Bahram oglu; Aben, Rosemarie; Abi, Babak; Abolins, Maris; AbouZeid, Hass; Abramowicz, Halina; Buanes, Trygve; Dale, Ørjan; Eigen, Gerald; Kastanas, Alex; Liebig, Wolfgang; Lipniacka, Anna; Martin dit Latour, Bertrand; Rosendahl, Peter Lundgaard; Sandaker, Heidi; Sjursen, Therese B.; Smestad, Lillian; Stugu, Bjarne; Ugland, Maren; Bugge, Lars; Bugge, Magnar Kopangen; Cameron, David Gordon; Catmore, James Richard; Czyczula, Zofia; Franconi, Laura; Gjelsten, Børge Kile; Gramstad, Eirik; Ould-Saada, Farid; Pajchel, Katarina; Pedersen, Maiken; Read, Alexander Lincoln; Røhne, Ole Myren; Stapnes, Steinar; Strandlie, Are; Abreu, Henso; Abreu, Rômulo F.; Abulaiti, Yiming; Acharya, Bobby S.; Adamczyk, Leszek; Adams, David; Adelman, Jareed; Adomeit, Stefanie; Adye, Tim; Agatonovic-Jovin, Tatjana; Aguilar Saavedra, Juan Antonio; Agustoni, Marco; ATLAS, Collaboration (Springer, 2015-04-23)
      The mass of the top quark is measured in a data set corresponding to 4.6 fb$^{−1}$ of proton--proton collisions with centre-of-mass energy $\sqrt{s}=7$ TeV collected by the ATLAS detector at the LHC. Events consistent with ...

    • Search for SUSY signals with tau leptons in the ATLAS detector 

      Sjursen, Therese Berge (The University of Bergen, 2008-02-15)
      The main topic of this thesis is the study of the discovery potential of the ATLAS detector for SUSY, by considering a supersymmetric decay chain involving two tau leptons. In supersymmetric models where R-parity is ...
