  1. 1. Derivation of Improved K^0_L Response Uncertainty for use in the Jet Energy Scale Calibration at ATLAS

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikelfysik

    Författare :Alexander Ekman; [2019]
    Nyckelord :kaon; neutral kaon; K^0_L; K_Long; klong; single-particle response; response; detector response; calorimeter; ATLAS; CERN; jets; trigger level analysis; TLA; physics list; Monte Carlo; MC; Physics and Astronomy;

    Sammanfattning : The Standard Model of particle physics (SM) attempts to describe the fundamental particles and how they interact with each other. This model is however incomplete, as shown by various experimental observations. ATLAS is one of the experiments currently in operation at the Large Hadron Collider, which aims to search for new physics beyond the SM. LÄS MER

  2. 2. Compilation and evaluation of validations of computer codes for spent nuclear fuel – a review

    Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Staffan Fors; [2019]
    Nyckelord :Nuclear fuel; Kärnbränsle; Slutförvar; Fissionsprodukter; Physics and Astronomy;

    Sammanfattning : This report describes a systematic review regarding validations of calculations by measurements of isotopic compositions, or decay heat, on spent nuclear fuel, SNF. 15 relevant or otherwise interesting studies, were found. Two reports were chosen among the found studies and analyzed. LÄS MER

  3. 3. Development of a DC Beam Model for the First Prototype of the ESS Virtual Machine

    Magister-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Nyckelord :Particle; Accelerator; Beam; Physics; Science; Virtual Machine; Virtual; Machine; Physics and Astronomy;

    Sammanfattning : The European Spallation Source is currently under construction in Lund, Sweden. Consisting of a linear accelerator delivering an unprecedented 5 MW proton beam to the spallation source, i.e. LÄS MER

  4. 4. Studies of Possible QGP Estimators in proton-proton Collisions

    Master-uppsats, Lunds universitet/Partikelfysik; Lunds universitet/Fysiska institutionen

    Författare :Anna Önnerstad; [2019]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : This thesis presents studies of three different Quark-Gluon Plasma estimators in proton-proton collisions using what is currently believed to be quark-gluon plasma observables; radial flow, elliptic flow and strangeness enhancement. The three tested estimators were Transverse Spherocity, an altered version of Transverse Spherocity where all p_T was put to one, and a newly developed estimator called Mid-Forward. LÄS MER

  5. 5. Fitting the three loop pion mass and decay constant to lattice data

    Kandidat-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik; Lunds universitet/Teoretisk partikelfysik; Lunds universitet/Institutionen för astronomi och teoretisk fysik

    Författare :Alexandra Wernersson; [2019]
    Nyckelord :Chiral Perturbation Theory; Lattice QCD; pion mass; decay constant; three loop fit.; Physics and Astronomy;

    Sammanfattning : We perform a fit to three loop order (NNNLO) in Chiral perturbation theory of the pion mass and decay constant. In particular we investigate if the NNNLO fit is an improvement of the fit to two loop order (NNLO) to lattice QCD data, which was done in a lattice gauge group collaboration. LÄS MER
