  1. 1. Search for Supersymmetry and Large Extra Dimensions with the ATLAS Experiment

    Författare :Gabriele Bertoli; Christophe Clement; Martijn Mulders; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ATLAS; CERN; large extra dimensions; supersymmetry; compressed; squark; neutralino; monojet; ADD; standard model; fysik; Physics;

    Sammanfattning : The Large Hadron Collider is the most powerful particle accelerator built to date. It is a proton-proton and heavy ion collider which in 2015 and 2016 operated at an unprecedented center of mass energy of √s = 13 TeV. The Tile Calorimeter is the ATLAS hadronic calorimeter covering the central region of the detector. LÄS MER

  2. 2. 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

  3. 3. Search for Direct Top Squark Pair Production with the ATLAS Experiment and Studies of the Primary Vertex Reconstruction Performance

    Författare :Yiming Abulaiti; Sara Strandberg; Robert Wagner; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SUSY;

    Sammanfattning : The ATLAS detector is one of the two largest experiments installed at the Large Hadron Collider at CERN, the European Organization for Nuclear Research. During the first run, the ATLAS detector recorded data at centre of mass energies of 7 TeV and 8 TeV, enabling many precision measurements and new physics searches. LÄS MER

  4. 4. A search for Supersymmetry in final states with two same-flavor opposite-sign leptons, jets and missing transverse momentum with the ATLAS detector

    Författare :Giulia Ripellino; Bengt Lund-Jensen; Strandberg Jonas; Mikko Voutilainen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ATLAS; LHC; supersymmetry; Fysik; Physics;

    Sammanfattning : This thesis presents a search for Supersymmetry in final states containing two same-flavor opposite-sign leptons, jets and large missing transverse momentum. The search makes use of 36.1 fb−1 of proton-proton collision data collected at a center-of-mass energy of √s = 13 TeV by the ATLAS detector at the Large Hadron Collider. LÄS MER

  5. 5. Search for Supersymmetry in Monojet Final States with the ATLAS Experiment

    Författare :Gabriele Bertoli; Christophe Clement; Joakim Edsjö; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ATLAS supersymmetry dark matter; Physics; fysik;

    Sammanfattning : The Large Hadron Collider is the most powerful particle accelerator built to date. The LHC is a proton–proton and heavy ion collider, in 2015 it operated at an un- precedented center of mass energy of sqrt(s) = 13 TeV. LÄS MER
