1. 1. Spinor-Helicity Formalism and ScatteringAmplitudes in Various Dimensions

   Master-uppsats, Uppsala universitet/Teoretisk fysik

   Författare :Chen Huang; [2023]
   Nyckelord :;

   Sammanfattning : In recent decades, spinor-helicity formalism has gained popularity as a useful tool for studyingscattering amplitudes in four dimensions. This formalism has been extended to higher dimensions,but there is still much work to be done around its application. LÄS MER

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

   Master-uppsats, Uppsala universitet/Teoretisk fysik

   Författare :Cesar Garcia; [2021]
   Nyckelord :String Theory; Twistors; Spinor-helicity variables;

   Sammanfattning : 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. LÄS MER
