1. 1. Pure Yang-Mills amplitudes in 5 Dimensions : A study of vector boson amplitudes at 4 and 5 points

   University essay from Uppsala universitet/Teoretisk fysik

   Author : Athanasios Voutouras; [2023]
   Keywords : Yang-Mills; Scattering; Amplitudes; QFT;

   Abstract : In this text we explore the case of pure Yang-Mills amplitudes in 5 spacetime dimensions for vector particles. Extending current toolsets such as the Spinor-Helicity formalism in 5D would be beneficial to the study of the various cases of super Yang-Mills and supergravity. READ MORE

3. 2. Leading Regge trajectory bosons in the pure spinor formalism

   University essay from Uppsala universitet/Teoretisk fysik

   Author : Erik Raab; [2018]
   Keywords : ;

   Abstract : We use a map introduced by Berkovits to determine the first levels of the theta-expansion of vertex operators for leading Regge trajectory bosons in the pure spinor formalism. This expansion is then used to confirm that in the pure spinor formalism, the 3-point disc scattering of any leading Regge trajectory bosons reproduces the corresponding Ramond-Neveu-Schwarz result found by Schlotterer.

4. 3. 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
