  1. 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

    Sammanfattning : 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. LÄS MER

  3. 2. Study of the production of π, K and p in pp collisions at √s = 13 TeV as a function of the Transverse Spherocity and the Relative Transverse Activity

    Författare :Omar Vazquez Rueda; Partikel- och kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LHC; ALICE; Quark-Gluon Plasma; Small Systems; pp Collisions; Underlying Event; Transverse Spherocity; Relative Transverse Activity; Fysicumarkivet A:2022:Vázquez Rueda;

    Sammanfattning : High-energy heavy-ion collisions allow the Quark-Gluon Plasma (QGP) production and study, a state of high-density QCD matter in which quarks and gluons are no longer confined inside hadrons for a very short time. Different observables reveal an enhanced production of strange hadrons, signatures of collective effects and opacity to jets due to the QGP formation. LÄS MER

  4. 3. Production of strangeness in partonic interactions at the LHC

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

    Sammanfattning : 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. LÄS MER

  5. 4. The Shape of Strangeness: Transverse Spherocity and Underlying Event studies of φ and its relation to Ξ in √s = 13 TeV pp collisions

    Författare :Adrian Nassirpour; Partikel- och kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LHC; ALICE; Quark-Gluon Plasma; small systems; pp collisions; underlying event; event-shape engineering; transverse activity; strangeness enhancement; resonance production; Fysicumarkivet A:2022:Nassirpour;

    Sammanfattning : Through ultrarelativistic particle collisions at the LHC, it is possible to deconfine quarks and gluons. This deconfinement gives rise to a strongly interacting medium, referred to as the Quark-Gluon Plasma (QGP). LÄS MER
