  1. 6. Studying Elliptic Flow in High Centrality Pb-Pb Collisions using Proton Collision Background Fitting

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

    Author : Philip Fredholm; [2023]
    Keywords : Physics and Astronomy;

    Abstract : In this report, the elliptic flow in high centrality Pb-Pb collisions is calculated using two particle correlations $v_2\{2\}$ but without any imposed separation in η with data taken from the ALICE experiment at CERN in 2015. Instead, measurements of the same correlations in proton-proton collisions is used as a background to account for non-flow effects and data is correlated between the time projection chamber and the forward multiplicity detectors in order to avoid intra-jet correlations.

  3. 7. Non-Diffractive Nuclear Excitations In Angantyr

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Carl Rosenkvist; [2023]
    Keywords : Heavy-ion; non-diffractive; nuclear excitation; secondary interactions; Physics and Astronomy;

    Abstract : To better understand collectivity in high energy physics, the heavy-ion collision model Angantyr was developed to be included in the event generator Pythia. In this model, proton-proton collision phenomenology is extrapolated to heavy-ion collisions without assuming a thermal plasma for particle production. READ MORE

  4. 8. Upgrade of the LHCb simulation framework with advanced particle event generators

    University essay from KTH/Fysik

    Author : Ruben Pozzi; [2023]
    Keywords : ;

    Abstract : The LHCb experiment is one of the main detectors in function at the Large Hadron Collider (LHC) at CERN. In order to interpret the data recorded by the detector, Monte Carlo (MC) samples are used as a way to validate and test theories by comparison with the experimental data. READ MORE

  5. 9. ATLAS Inner Tracker Upgrade for HL-LHC: Silicon microstrip detector metrology

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

    Author : Xiangyu Xu; [2023]
    Keywords : High energy physics experiment; LHC; HL-LHC; ATLAS; ITk; Metrology; Measurement; Physics and Astronomy;

    Abstract : The Large Hadron Collider (LHC) will be upgraded to the High-Luminosity LHC (HL-LHC) by the end of this decade, with five times larger luminosity and 200 inelastic collisions per proton-proton bunch crossing. Thus, the ATLAS detector is challenged to survive the stronger radiation and the increased particle flux. READ MORE

  6. 10. Forward-Backward Multiplicity Correlations for Proton-Proton Collisions with ALICE at LHC-CERN

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

    Author : August Koppers; [2022]
    Keywords : ALICE; Particle physics; CERN; LHC; QCD; pp collisions; Lund string model; Two particle correlation; Physics and Astronomy;

    Abstract : This thesis presents the study of two-particle pseudorapidity correlations in pp-collisions at √s = 13 TeV using the ALICE detector at LHC, CERN. The correlation function was calculated as a function of multiplicity and was repeated for several multiplicity classes and different charge combinations in the forward-backward and central regions of the detector, respectively.
