  2. 2. Potential for B-physics measurements with a fixed-target proton-collision experiment

    Detta är en avhandling från Department of Elementary Particle Physics, Lund University

    Författare :Jenny Ivarsson; Lund University.; Lunds universitet.; [1999]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Elementary particle physics; CP Violation; quantum field theory; Elementarpartikelfysik; HERA-B; Fixed Target; kvantfältteori; B Physics; Monte Carlo Simulations; Fysicumarkivet A:1999:Ivarsson;

    Sammanfattning : HERA-B is a high-energy physics experiment at HERA. It is a fixed-target experiment with a forward spectrometer to benefit from the strong boost of beauty hadrons. The main goal of HERA-B is to detect and measure the degree of CP violation in exclusive B-decays, with emphasis on the {em golden} decay, $golden$. LÄS MER

  3. 3. Luminosity evaluation and fragmentation studies for the DELPHI experiment at LEP

    Detta är en avhandling från Department of Physics, Lund University

    Författare :Christina Zacharatou Jarlskog; Lund University.; Lunds universitet.; [2001]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; luminosity; hadronization; Z boson; strong coupling constant; Elementary particle physics; Elementarpartikelfysik; quantum field theory; Fysicumarkivet A:2001:Jarlskog; LEP; DELPHI; kvantfältteori; Physics; Fysik;

    Sammanfattning : The first subject addressed in this thesis is the contribution of the VSAT luminosity to the lineshape analysis, i.e. to the extraction of the mass and width of the Z0 boson from LEP1 DELPHI data. The VSAT detector has contributed to the lineshape parameter determination by providing a relative luminosity measurement of high accuracy. LÄS MER

  4. 4. Measurement of azimuthal asymmetries in the hadronic final-state of deep inelastic scattering at HERA

    Detta är en avhandling från Department of Physics, Lund University

    Författare :Magnus Lindström; Lund University.; Lunds universitet.; [2000]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; jets; DIS; azimuthal asymmetries; structure function; unfold; quantum field theory; Elementary particle physics; Elementarpartikelfysik; kvantfältteori; Physics; Fysik; Fysicumarkivet A:2000:Lindström;

    Sammanfattning : Azimuthal asymmetries of the hadronic final state in deep inelastic scattering at HERA provide the opportunity to study the helicity of the interacting particles. We present a theoretical overview of the origin of these effects up to leading order in the strong coupling constant, $alpha_s$. LÄS MER
