A Pure Spinor Twistor Description of the Superparticle
Diego García Sepúlveda, Max Guillen
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 redefin…

A Pure Spinor Twistor Description of Ambitwistor Strings
Diego García Sepúlveda, Max Guillen
We present a novel ten-dimensional description of ambitwistor strings. This formulation is based on a set of supertwistor variables involving pure spinors and a set of constraints…

A Soft Theorem for the Tropical Grassmannian
Diego García Sepúlveda, Alfredo Guevara
We study the soft limit of a recently proposed generalization of the biadjoint scalar amplitudes , which have been conjectured to have a relation to the tropical Grass…
