Author : Lars-Ove Jönsson; Matematisk fysik; []
Keywords : NATURVETENSKAP; NATURAL SCIENCES; Matematisk och allmän teoretisk fysik; thermodynamics; statistical physics; gravitation; cranked Nilsson-Strutinsky; superdeformation; necked-in shapes; RPA; giant dipole resonance; finite-range liquid drop model; Mathematical and general theoretical physics; classical mechanics; relativity; quantum mechanics; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik; Fysicumarkivet A:1997:Jönsson;
Abstract :
Superdeformation, i.e. elongated shapes with the longest axis approximately twice as long as the shorter axes, has provided many new insights in nuclear structure. In this dissertation the possibility of forming superdeformed states related to two connected spheres, having a more or less pronounced neck, is investigated. READ MORE

Author : Lennart B Karlsson; Matematisk fysik; []
Keywords : NATURVETENSKAP; NATURAL SCIENCES; statistical physics; gravitation; superdeformation; Nilsson-Strutinsky; modified oscillator potential; moments of inertia; transition energies; rotational bands; quadrupole moments; spin assignments; identical bands; additivity.; Mathematical and general theoretical physics; classical mechanics; relativity; quantum mechanics; kvantmekanik; klassisk mekanik; thermodynamics; Matematisk och allmän teoretisk fysik; termodynamik; relativitet; statistisk fysik; Fysicumarkivet A:1999:Karlsson;
Abstract :
Many high spin rotational bands in superdeformed nuclei have been found in the A ~ 140-150 region, but so far no linking transitions to known normal-deformed states have been found in these nuclei. Therefore, configuration and spin assignments have to be based on indirect spectroscopic information. READ MORE

Keywords : NATURVETENSKAP; NATURAL SCIENCES; cosmic rays; event generators; colour factors; High energy interactions; hadronic jets; QCD; the Linked Dipole Chain model; quantum mechanics; relativity; gravitation; statistical physics; thermodynamics; Matematisk och allmän teoretisk fysik; kvantmekanik; klassisk mekanik; Kosmisk strålning; högenergi; classical mechanics; Mathematical and general theoretical physics; relativitet; statistisk fysik; termodynamik; Fysicumarkivet A:1997:Kharraziha;
Abstract :
In this thesis, we give a description of the detailed structure of the proton and a description of the final-state properties in electron-proton scattering. Qualitative results, in a purely gluonic scenario with the leading log approximation, and quantitative results, where quarks are included and some sub-leading corrections have been made, are presented.

Author : Astri Kleppe; Matematisk fysik; []
Keywords : NATURVETENSKAP; NATURAL SCIENCES; relativitet; kvantmekanik; klassisk mekanik; Matematisk och allmän teoretisk fysik; massive neutrinos; fermion masses; Mathematical and general theoretical physics; self-dual fields; democratic family mixing; quantum mechanics; classical mechanics; relativity; gravitation; thermodynamics; statistical physics; statistisk fysik; termodynamik; Elementary particle physics; quantum field theory; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:1997:Kleppe;
Abstract :
This thesis deals with different types of chiral fields. The properties of fermion masses are investigated from different poits of view, both within the Standard Model and in extensions of the model. It is shown how mass matrix invariants are used to define the measurables of the quark mixing matrix as invariant functions of the mass matrices. READ MORE
