  2. 1. Identified Hadron Production as a Function of Event Multiplicity and Transverse Spherocity in pp Collisions at √s = 7 and 13 TeV with the ALICE Detector

    Author : Vytautas Vislavicius; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LHC; ALICE; small systems; QGP; collectivity; multiplicity; spherocity; event shapes; pp collisions; Fysicumarkivet A:2018:Vislavicius;

    Abstract : This study reports on identified hadron production as a function of event multiplicity (dNch/dη) and transverse spherocity (SO) in proton-proton collisions at √s = 7 and 13 TeV measured with the ALICE detector at the LHC. The particle spectra and their ratios measured in high-multiplicity events show signatures of an expanding medium. READ MORE

  4. 2. Investigation of Quark Gluon Plasma-like signals with Lund string interactions

    Author : Smita Chakraborty; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; QCD; Phenomenology; Heavy-ion collisions; QGP-like signals; Proton-proton collisions; Jets; Fysicumarkivet A:2022:Chakraborty;

    Abstract : This thesis investigates the interactions that occur in extreme densities for high-energy collisions of subatomic particles. The theoretical models developed for this purpose are based on the Lund model. The developments have been implemented as a new module called Gleipnir to the Monte-Carlo event generator, P YTHIA .

  5. 3. Net-Charge Fluctuations in Ultra-Relativistic Nucleus-Nucleus Collisions

    Author : Henrik Tydesjö; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quark-Gluon Plasma; Net-Charge Fluctuations; Pad Chamber; högenergi; Kosmisk strålning; High energy interactions; cosmic rays; PHENIX; Heavy-Ion Collisions; RHIC; Fysicumarkivet A:2004:Tydesjö;

    Abstract : PHENIX is one of four experiments at the Relativistic Heavy-Ion Collider, RHIC. The high-energy heavy-ion collisions provided by this accelerator offer the possibility to study nuclear matter at high temperature and density. The high multiplicity of particles produced in these collisions puts high demands on detector performance. READ MORE

  6. 4. Study of Ξ-Hadron Correlations in pp Collisions at √s = 13 TeV Using the ALICE Detector

    Author : Jonatan Adolfsson; Fysiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LHC; ALICE; quark gluon plasma; small systems; pp collisions; strangeness enhancement; correlations;

    Abstract : By colliding heavy nuclei at high energies, which is done at RHIC and the LHC, a strongly interacting Quark Gluon Plasma (QGP) is created. This manifests itself through several different signatures, which until recently was thought to uniquely probe the QGP. READ MORE

  7. 5. Production of strangeness in partonic interactions at the LHC

    Author : Oliver Matonoha; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; quantum chromodynamics; quark-gluon plasma; neutral strange particles; small systems; transverse spherocity; underlying event; Fysicumarkivet A:2023:Matonoha;

    Abstract : The strong interaction is responsible for nearly all observable baryonic matter in the Universe. Quantum Chromodynamics, which describes interactions between quarks and gluons, however, cannot be solved analytically in the non-perturbative regime, involving low momentum transfers. READ MORE
