  1. 6. Understanding Rt using two-particle correlations by simulating proton-proton collisions in a Monte-Carlo model

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

    Author : Johan Leygonie; [2021]
    Keywords : QGP; Quark-Gluon-Plasma; Rt; Particle Physics; Proton-proton Collisions; Pythia; Monte-Carlo Model; Bachelor s Thesis; Heavy-ion Collisions; ALICE; CERN; Relative Transverse Activity; Jets; Two-Particles Correlations; Quantum Physics; Physics and Astronomy;

    Abstract : The observable Rt is investigated in the Monte Carlo Model Pythia in order to better understand results from experimental data obtained in the ALICE detector at CERN. The purpose is to reproduce the experiment in a simulation and use the features proposed by Pythia to dig into the unexpected outcomes. READ MORE

  3. 7. The impact of initial state radiation on jets from PbPb collisions

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Hilmi Kycyku; [2021]
    Keywords : heavy-ion physics; QGP; quark-gluon plasma; kvark-gluon plasma; initial state radiation; jets; medium response; Physics and Astronomy;

    Abstract : This thesis presents the study of how initial state radiation impacts jets produced in pp and PbPb collisions, by investigating the transverse momentum spectra, the rapidity spectra and the differential jet shape. This is done for central collisions with nucleon-nucleom COM energy 2.76 TeV and 5.02 TeV. READ MORE

  4. 8. J/psi suppression via string interactions in Au-Au collisions at 200 GeV/NN

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Julian Boy; [2020]
    Keywords : Suppression; gold-gold collisions; string interactions; fluxtubes nuclear modification factor; Physics and Astronomy;

    Abstract : In 2018 the Relativistic Heavy Ion Collider (RHIC) reported sig- nals of a strongly coupled quark gluon plasma. This plasma is thought to be the reason for J/psi suppression when a fraction of the produced J/psi's dissolves due to the high-energy density of quarks and gluons. READ MORE

  5. 9. Principal Component Analyses of Final States in Relativistic Nuclear Collisions using PYTHIA/Angantyr

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Nicoline Krogh Hemme; [2020]
    Keywords : Relativistic Nuclear Collisions; Heavy-ion Collisions; Pythia; Angantyr; String Shoving; Colour Reconnection; Principal Component Analysis; Anisotropic Flow; Elliptic Flow; Event-by-event Fluctuations; Physics and Astronomy;

    Abstract : We develop a program to perform a principal component analysis of flow fluctuations using simulations of nuclear collisions produced by the PYTHIA/Angantyr event generator. We consider both p+p and p+Pb collision events and study the leading and subleading modes of the second flow harmonic. READ MORE

  6. 10. Xi Production in pp Collisions at Different Multiplicity and Spherocity

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

    Author : Martin Angelsmark; [2019]
    Keywords : Particle Physics Quark Gluon Plasma ALICE LHC CERN Xi Baryon Transverse Spherocity Multiplicity; Physics and Astronomy;

    Abstract : The protons and neutrons that make up the atoms in our Universe are part of a larger group of particles called hadrons. Hadrons have an inner structure consisting of the elementary particles called quarks. The interaction of the quarks is described by the quantum field theory quantum chromodynamics. READ MORE
