  1. 1. Studies of Nuclear Matter under Extreme Conditions: Heavy-Ion Interactions at Ultra-Relativistic Energies

    Författare :Joakim Nystrand; Partikel- och kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; heavy-ion interactions; quark-gluon plasma; nuclear emulsion; multi-step avalanche chambers; particle production; transverse momentum distributions; intensity interferometry; nucleus-nucleus collisions; rapidity distributions; Physics; Fysik; Fysicumarkivet A:1996:Nystrand;

    Sammanfattning : The charged particle production in ultra-relativistic nucleus-nucleus collisions in the energy range 4-200 A GeV has been studied. Two different experimental techniques have been utilized: nuclear emulsions and Multi-Step Avalanche Chambers. LÄS MER

    Sammanfattning : The Higgs particle was first predicted in 1964, and was discovered in the summer of 2012 at the Large Hadron Collider (LHC). This discovery was the latest in a long list of successful Standard Model predictions spanning the last fifty years. LÄS MER

  4. 3. Charged particle multiplicities in p̄p reactions 540 GeV C.M. energy

    Författare :Barbro Åsman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Antiproton-proton reactions at a centre of mass energy of 540 GeV are studied. The results were obtained using the UA5 detector installed at the CERN SPS Collider.The pseudorapidity (-n) distribution for non single-diffractive events is presented and compared to ISR data.

  5. 4. Multiparticle Production in Strong Interactions

    Författare :Fredrik Söderberg; Centrum för miljö- och klimatvetenskap (CEC); []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hadronisation; QCD; Bose-Einstein correlations; Elementary particle physics; Elementarpartikelfysik; quantum field theory; String fragmentation; kvantfältteori; Fysicumarkivet A:2003:Söderberg;

    Sammanfattning : An alternative formulation of the Lund fragmentation model for string states without gluons is presented. It is shown that the fragmentation process can be factorised into a product of transition operators with well-defined eigenfunctions and corresponding eigenvalues. LÄS MER
