  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. Signal background interference effects in lepton trident events with a new low mass mediator

    University essay from Lunds universitet/Teoretisk partikelfysik

    Author : Patricia Andrea Gutiérrez García; [2020]
    Keywords : dark matter; pythia; matrix element corrections; LDM; Dire; Madgraph; dark photons; Physics and Astronomy;

    Abstract : In this project we present a phenomenological study of signal to background interference effects in leptonic tridents produced in parton showers. The interference effects are introduced by linking matrix element corrections of a kinetically mixed dark photon model to the parton shower Dire. READ MORE

  4. 4. 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

  5. 5. Studies of Possible QGP Estimators in proton-proton Collisions

    University essay from Lunds universitet/Partikelfysik; Lunds universitet/Fysiska institutionen

    Author : Anna Önnerstad; [2019]
    Keywords : Physics and Astronomy;

    Abstract : This thesis presents studies of three different Quark-Gluon Plasma estimators in proton-proton collisions using what is currently believed to be quark-gluon plasma observables; radial flow, elliptic flow and strangeness enhancement. The three tested estimators were Transverse Spherocity, an altered version of Transverse Spherocity where all p_T was put to one, and a newly developed estimator called Mid-Forward. READ MORE
