Ambitwistor superstring in the Green–Schwarz formulation

In this paper we construct the ambitwistor superstring in the Green–Schwarz formulation. The model is obtained from the related pure spinor version. We show that the spectrum contains only ten-dimensional supergravity and that kappa symmetry in a curved background implies some of the standard constraints.

Master symmetry in the AdS 5 × S 5 pure spinor string

We lift the set of classical non-local symmetries recently studied by Klose, Loebbert, and Münkler in the context of ℤ 2 cosets to the pure spinor description of the superstring in the AdS 5 × S 5 background.
