  1. 11. Performance of jet subtraction in pPb and PbPb collisions, without collectivity

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Sebastian Grabowski; [2018]
    Keywords : heavy ion: scattering; Angantyr; underlying event; subtraction; jet: quenching; non-collectivity; stacking; jet: correlation; non-colliective; background; Physics and Astronomy;

    Abstract : We investigated the performance of basic jet subtraction, by the utilization of jet reconstruction generally used at the Large Hadron Collider (LHC). This was done by studying Z-bosons, in the dielectron decay channel, and the associated jet correlation in pp, pPb and PbPb collisions, using datasets generated by the Monte Carlo generator PYTHIA8.

  3. 12. Electrons from heavy- flavor semileptonic decays in proton-proton collisions at √s=13 TeV measured with the ALICE detector at the LHC

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Author : Madeleine Petersson Sjögren; [2018]
    Keywords : LHC ALICE Heavy-ion physics particle physics heavy-flavor; Physics and Astronomy;

    Abstract : Heavy-flavor hadrons, containing charm and bottom quarks, serve as a tool available for the characterization of the hot and dense strongly interacting Quark Gluon Plasma state of matter, produced in heavy-ion collisions. As a benchmark for heavy-ion collision measurements, proton-proton collisions are also studied. READ MORE

  4. 13. The space--time structure of hadron production in high-energy collisions

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Silvia Ferreres; [2018]
    Keywords : event generator; space--time implementation; hadron production; hadron density; space--time; Physics and Astronomy;

    Abstract : In this thesis, the space--time picture of the hadronization model has been implemented in the event generator Pythia. From this implementation, the hadronic behaviour has been studied for different scenarios, in order to begin addressing the unexpected collective behaviour of high-multiplicity pp events, which is typical for heavy-ion collisions.

  5. 14. Elliptic Flow Studies using Event Shape Engineering in Pb-Pb Collisions at ALICE

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Author : Rickard Lydahl; [2017]
    Keywords : Elliptic Flow; ALICE; Event Shape Engineering; Pb-Pb; lead-lead; Particle physics; Physics and Astronomy;

    Abstract : Inn ultra-relativistic heavy-ion collisions, QCD matter undergoes a phase transition to a strongly interacting Quark Gluon Plasma (QGP) where quarks and gluons are deconfined. The expansion of this plasma is well described by ideal hydrodynamics, suggesting that it behaves like a perfect, reversible, liquid. READ MORE

  6. 15. Blast-Wave Model Studies in Pb-Pb Collisions at LHC

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Isabell Bågenholm; [2016]
    Keywords : Physics and Astronomy;

    Abstract : 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. READ MORE
