  1. 1. AdS/CFT correspondence and c-extremization

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Roberto Goranci; [2017]
    Keywords : AdS CFT; c-extremization; Super Yang-Mills; Supergravity; M5 membrane; Conformal field theory; Anomalies; superconformal CFT; 6d SCFT; black string; String theory; compactification;

    Abstract : In this project we review the method of using c-extremization and computing anomalies to obtain AdS/CFT theories. We start with a quick introduction to CFT's and AdS/CFT correspondence which gives us the tools to later understand the 2D N= (2,0) SCFT and its gravity duals in particular AdS_5xS^5 and AdS_7xS^4 compactified on Riemann surfaces. ..

  2. 2. Yang-Mills driven Cosmic Expansion

    University essay from Lunds universitet/Teoretisk partikelfysik; Lunds universitet/Institutionen för astronomi och teoretisk fysik

    Author : Jimmy Ljungberg; [2016]
    Keywords : Cosmic Inflation; Dark Energy; Yang-Mills; SU 2 gauge fields; Perturbations; Physics and Astronomy;

    Abstract : This thesis will investigate the possibility to have SU(2) gauge fields as the source to the Cosmic Inflation and/or to the Dark Energy. It will be explained that, under certain conditions, the Universe can be filled with vector fields without violating its isotropy. Those conditions are naturally fulfilled within the SU(2) gauge theory. READ MORE

  3. 3. Localization Techniques, Yang-Mills Theory and Strings

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Linnea Svensk; [2016]
    Keywords : ;

    Abstract : Equivariant localization techniques exploit symmetries of systems, represented by group actions on manifolds, and use them to evaluate certain partition functions exactly. In this master thesis we begin with the study of localization in finite dimensions. READ MORE

  4. 4. Tree-Level N-Point Amplitudes in String Theory

    University essay from Uppsala universitet/Teoretisk fysik

    Author : John Paton; [2016]
    Keywords : string theory; pure spinors; pure spinor formalism; amplitudes; N-point; BRST;

    Abstract : This thesis reviews the method of Mafra, Schlotterer, and Stieberger (2011) for computing the full colour ordered N-point open superstring amplitude using the Pure Spinor formalism. We introduce relevant elements of super Yang-Mills theory and examine the basics of the Pure Spinor formalism, with a focus on tools for amplitude computation. READ MORE

  5. 5. Browsing the Web of Amplitudes

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Alexander Söderberg; [2016]
    Keywords : amplitude; amplitudes; relation; relations; browsing; web; bcj; kk; double; copy; zeroth; klt; single; valued; projection; quantum; field; theory; qft; string; type; I; II; heterotic;

    Abstract : We begin by studying field-theory amplitude relations such as the Kleiss-Kuijf, Bern-Carrasco-Johansson, Kawai-Lewellen-Tye and the double copy construction, which are important ingredients in this thesis. Going beyond the field-theory limit we study how the gauge-sector of the heterotic string relates to type I amplitudes through the single valued projection of multiple zeta values. READ MORE
