  1. 1. Non-Diffractive Nuclear Excitations In Angantyr

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

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

    Sammanfattning : 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. LÄS MER

  3. 2. On the Energy Dependence of Parameters in PYTHIA8 Heavy-ion Collision Simulations

    Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Felipe Abedrapo; [2022]
    Nyckelord :Heavy-ion Collisions; PYTHIA; Angantyr; Physics and Astronomy;

    Sammanfattning : Particle collisions are an essential component to the research methodology of particle physics. These investigations are not only conducted in experimental laboratories but also through programs such as PYTHIA that simulate a collision or ``event" and then compare its results to known experimental data.

  4. 3. Projections for charm balance functions in heavy-ion collisions

    Kandidat-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Tilde Bonnevier Wallstedt; [2022]
    Nyckelord :Heavy-ion physics; quark-gluon plasma; QGP; balance function; charm quark; Physics and Astronomy;

    Sammanfattning : In this thesis, pp collisions were simulated using PYTHIA. D+ D- and D0 D0bar balance functions were created in order to contribute with a reference point for future balance functions measured in real data from Pb-Pb collisions. LÄS MER

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

    Kandidat-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Johan Leygonie; [2021]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

    Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

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

    Sammanfattning : 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. LÄS MER
