A Pure Spinor Twistor Description of the D=10 Superparticle

Authors: Diego García Sepúlveda and Max Guillen Preprint number: UUITP-19/20 We present a novel twistor formulation of the ten-dimensional massless superparticle. This formulation is based on the introduction of pure spinor variables through a field redefinition of another model for the superparticle, and in the new description we find that the super-Pauli-Lubanski three-form naturally arises as a constraint. Quantization is studied in detail for both models and they are shown to correctly describe the D=10 super-Yang-Mills states.
