    Abstract : Popular Abstract in Swedish Partikelfysik och det vetenskapliga arvet Har du gått i en ljus vänlig skog om sommaren när vinden susar bland löven och små djur kilar omkring under gräset och solen skiner på din hud och kittlar din amygdala i det innersta av din hjärna? Har du någonsin reflekterat över naturens oändliga rikedom? Hur kan en värld vara uppbyggd som uppvisar en sådan komplexitet? Vill man beskriva den, måla av den eller dikta om den så kan man spendera en livstid utan att ändå lyckas fånga alla dess ansikten. I fysiken talar man om atomer, protoner och fundamentala krafter.

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

    University dissertation from Department of Physics, Lund University

    Author : Christina Zacharatou Jarlskog; Lunds universitet.; Lund University.; [2001]
    Keywords : 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;

    Abstract : 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. READ MORE
