  2. 1. Some Aspects of Chirality: fermion masses and chiral p-forms

    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

  4. 2. Torn, Spun and Chopped : Various Limits of String Theory

    Author : Fredric Kristiansson; Ulf Danielsson; Per Sundell; Bo Sundborg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical physics; Theoretical physics; String theory; D-branes; Non-commutative open string theory; AdS CFT; Higher spin gauge theory; BMN; String bits; Fermion doubling; Teoretisk fysik; Physics; Fysik;

    Abstract : For the first time in the history of physics we stand in front of a theory that might actually serve as a unification of it all - string theory. It provides a self-consistent framework for gravity and quantum mechanics, which naturally incorporates matter and gauge interactions of the type seen in the standard model. READ MORE

  5. 3. Linking Chains Together : String Bits and the Bethe Ansatz

    Author : Martin Lübcke; Konstantin Zarembo; Antti Niemi; Matthias Staudacher; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical physics; theoretical physics; string theory; string bit; Bethe ansatz; Teoretisk fysik; Physics; Fysik;

    Abstract : This thesis is divided into two parts. In the first part we focus mainly on certain aspects of the AdS/CFT correspondence. The AdS/CFT correspondence is a proposed duality between Type IIB superstring theory on AdS5 x S5 and N = 4 supersymmetric Yang-Mills theory. READ MORE
