Event details
Twistor variables for Anti-de Sitter (super)particles, strings and branes
We will show how (super)twistors for AdS_{d+1} spacetimes simplify the dynamics of (super)particles, strings and branes propagating on those geometries. An AdS_{d+1} twistor is a pair of Penrose twistors for d-dimensional Minkowski space (modulo certain identifications). We will see how the construction works for superparticles on AdS, yielding a 1st-quantized description of graviton supermultiplets, and outline the generalisation to tensionless p-branes. We will also indicate how this construction could be relevant to AdS/CFT and the "gravity=Yang-Mills squared" proposal.
