  1. 1. Development of the read-out link and control board for the ATLAS Tile Calorimeter Upgrade

    Author : Eduardo Valdés Santurio; Samuel Bryant Silverstein; Costas Foudas; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; HL-LHC; ATLAS; Tile Calorimeter; TileCal; Demonstrator; Daughterboard; Read-out; Digital electronics; Data acquisition; Radiation tolerant; GBTx; TID; NIEL; SEU; SEL; FPGA; Kintex 7; Ultrascale; Ultrascale ; Optic Links; Physics; fysik;

    Abstract : The Phase-II upgrade plan for the ATLAS Hadronic Tile Calorimeter facing the High-Luminosity LHC (HL-LHC) era includes approximately 1000 radiation tolerant read-out link and control boards (Daughterboards) that will provide full-granularity digital data to a fully-digital trigger system off-detector through multi-Gbps optic fibres. Different Daughterboard (DB) revisions have been developed, each successively aiming to meet the demanding HL-LHC requirements. READ MORE

  2. 2. Search for Charginos and Sleptons in ATLAS and Identification of Pile-up with the Tile Calorimeter

    Author : Pawel Klimek; Christophe Clément; Barbro Åsman; Freya Blekman; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; ATLAS experiment; particle physics; high energy physics; supersymmetry; SUSY; beyond standard model; chargino; neutralino; slepton; vector boson fusion; VBF; Tile calorimeter; TileCal; pile-up; quality factor; Large Hadron Collider; LHC; CERN; Physics; fysik;

    Abstract : The standard model of particle physics (SM) describes the elementary particles and their interactions. Supersymmetry (SUSY), a symmetry beyond those included in the standard model could resolve some of the SM shortcomings. It can provide a candidate for Dark Matter and a solution to the hierarchy problem. READ MORE

  3. 3. Search for Stop Using the ATLAS Detector and Performance Analysis of the Tile Calorimeter with Muons from W Decays

    Author : Stefio Yosse Andrean; Christophe Clement; Joakim Edsjö; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; particle physics; standard model; bsm; supersymmetry; stop; calorimeter; ATLAS; Physics; fysik;

    Abstract : This thesis presents a search for the supersymmetric partner of the top quark in the final state with one lepton. The search focuses especially in the region of the parameter space where the 2-body decay dominates. The analysis is performed using LHC full Run 2 data at √s = 13 TeV as recorded by the ATLAS detector. READ MORE

  4. 4. Development and Test of the ATLAS Tile Calorimeter Digitizer

    Author : Jonas Lesser; Christian Bohm; Lorne Levinson; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Physics; Fysik;

    Abstract : The new LHC particle accelerator now being built at CERN will have a radically increased event rate and higher energy. To accommodate this, instrumentation for LHC experiments has had to be constructed using new ideas and the latest available technology. READ MORE

  5. 5. Search for Dark Matter and Extra Dimensions in Monojet Final States with the ATLAS Experiment

    Author : Olof Lundberg; Christophe Clement; Chad Finley; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Dark Matter; LHC; ATLAS; Extra Dimension; Gravity; Calorimeter; högenergifysik; High Energy Physics;

    Abstract : The CERN Large Hadron Collider (LHC) is the most powerful particle ac- celerator ever built, in terms of luminosity and center-of-mass energy of the collisions. This thesis presents a search for Dark Matter and Extra Dimen- sions in the proton-proton collisions as recorded by the ATLAS detector. READ MORE
