  2. 1. Supersymmetric Gauge Theories and Matrix Models

    Author : Rainer Heise; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; String theory; Effective field theory; Matrix model; Supersymmetric gauge theories;

    Abstract : We discuss recent developments in supersymmetric field theory due to the conjecture of Dijkgraaf and Vafa relating the effective superpotential of such theories to the computation of an associated matrix model. We give a short survey of N=1 supersymmetric gauge theories and state the conjecture. READ MORE

  4. 2. Studies of effective theories beyond the Standard Model

    Author : Stella Riad; Tommy Ohlsson; Mattias Blennow; Johan Rathsman; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Effective field theories; neutrino physics; extra dimensions; universal extra dimensions; Higgs physics; renormalization group running; Bayesian statistics; coupling scale factor; grand unified theories;

    Abstract : The vast majority of all experimental results in particle physics can be described by the Standard Model (SM) of particle physics. However, neither the existence of neutrino masses nor the mixing in the leptonic sector, which have been observed, can be described within this model. READ MORE

  5. 3. Strings, Gravitons, and Effective Field Theories

    Author : Igor Buchberger; Marcus Berg; Joseph A. Minahan; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; string theory; amplitudes; supersymmetry; particle phenomenology; BMSSM; modified gravity; bimetric; massive gravity; Lie algebras; ribbon categories; Physics; Fysik;

    Abstract : This thesis concerns a range of aspects of theoretical physics. It is composed of two parts. In the first part we motivate our line of research, and introduce and discuss the relevant concepts. In the second part, four research papers are collected. READ MORE

  6. 4. Phenomenology of neutrino properties, unification, and Higgs couplings beyond the Standard Model

    Author : Stella Riad; Tommy Ohlsson; Nuria Rius; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Effective field theories; neutrino physics; extra dimensions; universal extra dimensions; Higgs physics; renormalization group running; Bayesian statistics; grand unified theories; Fysik; Physics;

    Abstract : The vast majority of experiments in particle physics can be described by the Standard Model of particle physics (SM). However, there are indications for physics beyond it. The only experimentally demonstrated problem of the model is the difficulty to describe neutrino masses and leptonic mixing. READ MORE

  7. 5. Conformal Field Theory Deformations and Supersymmetric D-brane Actions

    Author : Alexander von Gussich; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Over the past few years a dramatic progress in understanding non-perturbative phenomena in string theory has occurred. This is commonly referred to as the second string revolution. This thesis, consisting of an introduction and five appended research papers (I-V), deals with pre-revolutionary as well as post-revolutionary aspects of string theory. READ MORE
