  1. 1. Multi-Strange and Charmed Antihyperon-Hyperon Physics for PANDA

    Författare :Erik Thomé; Tord Johansson; Brian Quinn; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PANDA; FAIR; antiproton; hyperon; strangeness; charm; polarisation; spin correlation; CP violation; Nuclear Physics; Kärnfysik;

    Sammanfattning : The prospects of studying multi-strange and charmed antihyperon-hyperon physics and CP violation in hyperon decays in the upcoming PANDA experiment at FAIR, Germany, have been studied in this thesis.The angular dependence on polarisation parameters in the decay of the spin 3/2 Omega hyperon was calculated using the density matrix formalism.

  2. 2. 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

  3. 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

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

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

    Sammanfattning : 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. LÄS MER

  5. 5. Λ-Λ hyperons: the road to estimate the production cross-section in protonproton collisions

    Författare :Gandharva Appagere; Maria Doncel Monasterio; Per-Erik Tegnér; Michael Papenbrock; Andreas Heinz; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hyperons; multi-strangeness; neutron-stars; cross-section; Lambda-lambda; Physics; fysik;

    Sammanfattning : In this study, we analyse the $\Lambda$-$\Lambda$ hyperon channel in proton-proton scattering, $pp \mapsto \Lambda\Lambda + K^+K^+, \,\,\Lambda\mapsto p+\pi^-$, with a proton beam energy of $4.5$ GeV using the High Acceptance Di-Electron Spectrometer (HADES) at GSI. LÄS MER
