  2. 6. Extensions of general relativity : scalar tensor theory, topology of space-time and supergravity

    Author : Ulf Lindström; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This report together with Papers 1—11 constitute a dissertation on the subjects of Scalar Tensor Theories, Topology of Space-Time and Supergravity. These three areas are briefly introduced for providing a background to the work in 1—11. A general discussion of motivations for modifications of the Einstein theory is also offered. . READ MORE

    Abstract : Higher orders calculations of processes involving the pion and kaon pseudo-scalar mesons are presented in the framework of three flavour Chiral Perturbation Theory. The purpose is two-fold. First determining the low energy constants of ChPT that are necessary for higher accuracy predictions. READ MORE

    Abstract : The five different K -> 3 Pi and the three K -> 2 Pi decays are calculated in Chiral Perturbation Theory. The calculation is done using different approximations, to study whether this changes the result significantly. First the isospin approximation is used. Discrepancies are then found between theory and experiment. READ MORE
