  1. 21. 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

  3. 22. Searches for Low-Mass Dijet Resonances in Trijet Final States using Monte Carlo Samples

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

    Författare :Patrawan Pasuwan; [2016]
    Nyckelord :Dijet resonance; trijet final states; mass combination; sensitivity studies; composite quark model; simplifies dark matter mediator model; Physics and Astronomy;

    Sammanfattning : This thesis presents the prototype of a search for new phenomena that decay in two jets, in presence of an associated jet (three-jet or trijet final state). Mass combination studies are carried out to reconstruct dijet resonances in different mass regions. LÄS MER

  4. 23. Search for Jet Quenching in Pb-Pb collisions at s_NN = 2.76 TeV

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

    Författare :Adrian Nassirpour; [2015]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The purpose of this thesis is to further investigate the state of matter known as Quark-Gluon Plasma (QGP) that is produced in heavy ion collisions. This is done by analyzing jets and jet quenching in Pb-Pb collisions at $\sqrt[]{s_\textrm{NN}}$ = 2.76 TeV from ALICE. LÄS MER

  5. 24. Search for azimuthal anisotropic flow in proton-proton collisions

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

    Författare :Adam Johansson; [2015]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : In high energy heavy ion collisions a new state of matter called quark gluon plasma is produced. An important observable is azimuthal anisotropy flow. Data from the ALICE experiment is used in the search for azimuthal anisotropic flow in pp collisions, at $\sqrt{s_{NN}} = 7$ TeV. p--Pb collisions at $\sqrt{s_{NN}} = 5. LÄS MER

  7. 25. Comparison of dilepton events in simulation and $pp$ collision data at $\sqrt s = 8\tev$ gathered by the ATLAS detector at the LHC

    Master-uppsats, Uppsala universitet/Högenergifysik

    Författare :Max Isacson; [2014]
    Nyckelord :charged; higgs; boson; high energy physics; hep; monte carlo; collision data; dilepton; control region; atlas; lhc; leptons;

    Sammanfattning : This thesis presents the results of a comparison between collision data and simulations based on Monte Carlo methods. The experimental dataset consists of $20.3\,\mathrm{fb}^{-1}$ of proton-proton collision data at $\sqrt s = 8\tev$ collected during 2012 by the ATLAS experiment located at the Large Hadron Collider.
