  3. 17. On Experimental and Theoretical Studies of Dynamics and Particle Production in p+Nucleus and Heavy Ion Reactions

    Författare :Anton B Fokin; Partikel- och kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; heavy-ion collisions; excitation function; subthreshold pion production; collective effects; entropy and chaos production; d p ratio; molecular dynamics; artificial neural networks; multifragmentation; Physics; Fysik; Fysicumarkivet A:1998:Fokin;

    Sammanfattning : Several experiments and theoretical models of intermediate energy heavy ion collision physics are presented in this thesis. Statistical and dynamical aspects of nuclear collisions are widely discussed these days, particularly in connection with the multifragmentation phenomenon and the possible link to a liquid-gas phase transition in the spinodal region of nuclear matter phase diagram.

  4. 18. Measurements of the Standard Model Higgs boson cross sections in the WW* decay mode with the ATLAS experiment

    Författare :P. Edvin Sidebo; Jonas Strandberg; Markus Klute; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; p p: colliding beams; Higgs particle: hadroproduction; Higgs particle: decay; cross section: measured; High energy physics: experimental; Timing detectors; p p: scattering; ATLAS; Cern LHC Coll; Fysik; Physics;

    Sammanfattning : This thesis summarises measurements of the Standard Model Higgs boson production cross sections based on proton–proton collision data at √s = 13 TeV produced by the Large Hadron Collider at CERN. By analysing data collected during 2015 and 2016 by the ATLAS experiment, corresponding to an integrated luminosity of 36 fb−1, the Higgs boson gluon–gluon fusion and vector boson fusion production cross sections are measured in the WW* decay mode.

    Sammanfattning : Different hadronization effects in high energy interactions are investigated. The frame-work is the Lund model for the strong interaction. A model for baryon production in jet fragmentation is presented and extended to baryon remnant fragmentation in deep inelastic scattering and hadron--hadron collisions. LÄS MER
