  1. 1. Transverse Momentum Spectra in pp collisions (\sqrt{s}\) = 7 TeV and \(\sqrt{s}\) = 13 TeV in ALICE

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Författare :Andreas Stokkeland; [2023]
    Nyckelord :Multiplicity; Multiplicity classes; Soft interactions; Quark Gluon Plasma; QGP; transverse momentum; p_T; Chi-squared; fits; fit functions; Levy; Lévy; Exponential; BGBW; Boltzmann-Gibbs blast-wave; Fermi-Dirac; Bose-Einstein; Boltzmann; pion; kaon; proton; transverse momentum spectra; p_T spectra; surface velocity; Minimum Bias; MB; Physics and Astronomy;

    Sammanfattning : In this project particle production as a function of transverse momentum (\(p_{\rm T}\)) in proton-proton collisions at a center-of-mass energy (\(\sqrt{s}\)) of 7 TeV and 13 TeV has been studied. The transverse momentum is interesting to study since it reflects momentum created in the collision (before the collision, all momentum is in the beam - going in a longitudinal direction) and therefore gives information on the collision dynamics.

  2. 2. Validation of simulation with enhanced kaon production to investigate kaon background for LDMX

    Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Lisa Andersson Loman; [2023]
    Nyckelord :Dark matter; experimental physics; simulations; kaons; particle physics; LDMX; background studies; mörk materia; partikelfysik; kaoner; Physics and Astronomy;

    Sammanfattning : Dark matter is one of our universe’s largest mysteries and very little is known about what it is. One of the dominating theories, that it originates from an early universe thermal relic, indicates that it has interaction with the Standard Model. LÄS MER

  3. 3. Projections for charm balance functions in heavy-ion collisions

    Kandidat-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Tilde Bonnevier Wallstedt; [2022]
    Nyckelord :Heavy-ion physics; quark-gluon plasma; QGP; balance function; charm quark; Physics and Astronomy;

    Sammanfattning : In this thesis, pp collisions were simulated using PYTHIA. D+ D- and D0 D0bar balance functions were created in order to contribute with a reference point for future balance functions measured in real data from Pb-Pb collisions. LÄS MER

  4. 4. 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/Partikel- och kärnfysik

    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

  5. 5. Blast-Wave Model Studies in Pb-Pb Collisions at LHC

    Kandidat-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Isabell Bågenholm; [2016]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : In high-energy heavy-ion collisions, a state of matter called quark-gluon plasma (QGP) can be created. The production of particles from the QGP can be described by different models, one of these is the blast-wave model. The blast-wave model describes the production of particles from the QGP, not from jets. LÄS MER
