Twistors for Anti-de Sitter physics

We will introduce (super)twistors for AdS_d+1 spacetimes. An AdS_d+1 twistor is a pair of ordinary (conformal) twistors for d-dimensional Minkowski space (modulo certain identifications). We will show how twistors simplify the physics of massive and massless particles on AdS_d+1, and sketch how the twistor construction extends to tensionless strings and p-branes. For the p-brane case we will see that the theory is apparently topological.
