  1. 1. Exploring properties of a 10-dimensional pure spinor twistor transform

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Cesar Garcia; [2021]
    Keywords : String Theory; Twistors; Spinor-helicity variables;

    Abstract : In this review, several tools used in the study of super-Yang-Mills scattering amplitudes are discussed, namely spinor-helicity and (super)twistor variables. These variables are then implemented in string theories in 4D, and a suitable generalization to 10D using pure spinors is discussed. READ MORE

  3. 2. 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
