  2. 6. Multiple Parton Interactions in Deep Inelastic ep-scattering at HERA

    Author : Sakar Osman; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Jet Calibration; H1; Jets; Mini-jets; MPI; Low-x; Multiple; Dijets; Parton Dynamics; HERA; Fysicumarkivet A:2008:Osman;

    Abstract : The production of jets with low transverse momenta (mini-jets) in deep inelastic electron-proton scattering is studied. The analyses uses data taken with the H1 detector at HERA during the years 1999 to 2000. READ MORE

  4. 7. An Experimental Study on Melt Fragmentation, Oxidation and Steam Explosion during Fuel Coolant Interactions

    Author : Louis Manickam; Weimin Ma; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; severe accident; fuel coolant interactions; melt jet breakup; debris properties; steam explosion; oxidation; high-speed visualization; Physics; Fysik;

    Abstract : Nordic type boiling water reactors (BWRs) adopt reactor cavity flooding as a severe accident mitigation strategy (SAMS) to achieve core melt fragmentation and long-term cooling of decay heat generating core debris. The qualification of this SAMS needs to address two main severe accident issues: debris bed coolability and steam explosion. READ MORE

  5. 8. Multiparticle Production in Strong Interactions

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

    Abstract : 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. READ MORE

  6. 9. Parametric Model for Astrophysical Proton-Proton Interactions and Applications

    Author : Niklas Karlsson; Per Carlson; Simon Swordy; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; astrophysics; gamma rays; proton-proton interactions; cosmic rays; Astronomy and astrophysics; Astronomi och astrofysik;

    Abstract : Observations of gamma-rays have been made from celestial sources such as active galaxies, gamma-ray bursts and supernova remnants as well as the Galactic ridge. The study of gamma rays can provide information about production mechanisms and cosmic-ray acceleration. READ MORE

  7. 10. Exploring the Surface of Aqueous Solutions : X-ray photoelectron spectroscopy studies using a liquid micro-jet

    Author : Josephina Werner; Olle Björneholm; Ingmar Persson; Daniel Lundberg; Johan Söderström; Hendrik Bluhm; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; X-ray Photoelectron spectroscopy; liquid micro-jet; air-water interface; inorganic salt; carboxylic acid; alcohol; isomers; hydration.; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : The surface behavior of biologically or atmospherically relevant chemical compounds in aqueous solution has been studied using surface-sensitive X-ray photoelectron spectroscopy (XPS). The aim is to provide information on the molecular-scale composition and distribution of solutes in the surface region of aqueous solutions. READ MORE
