Spacecone quantization of AdS superparticle
arXiv:1005.5049
Abstract
We first-quantize the superparticle describing free 10D IIB supergravity on AdS_5xS^5. We choose the worldline coordinate to be a combination of the bulk (spatial) coordinates of anti de Sitter space and the sphere. The Hamiltonian is independent of this "time" and the fermions. On the boundary, the representation of PSU(2,2|4) becomes that of projective superspace. The prepotential propagator reproduces the known field-strength one.
