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

    University essay from Lunds universitet/Partikelfysik; 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

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

    University essay from Lunds universitet/Teoretisk partikelfysik

    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

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

    University essay from Lunds universitet/Teoretisk partikelfysik

    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

  4. 4. Xi Production in pp Collisions at Different Multiplicity and Spherocity

    University essay from Lunds universitet/Partikelfysik; 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

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

    University essay from Lunds universitet/Teoretisk partikelfysik; Lunds universitet/Institutionen för astronomi och teoretisk fysik

    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.
