A Simple Particle Action from a Twistor Parametrization of AdS_5
Piet Claus, J. Rahmfeld, Yonatan Zunger
The SO(4,2) isometries of AdS_5 are realized non-linearly on its horospherical coordinates (x^m,ρ). On the other hand, Penrose twistors have long been known to linearly realize the…

Supertwistors as Quarks of SU(2,2|4)
Piet Claus, Murat Gunaydin, Renata Kallosh +2
The GS superstring on AdS_5 x S^5 has a nonlinearly realized, spontaneously broken SU(2,2|4) symmetry. Here we introduce a two-dimensional model in which the unbroken SU(2,2|4) sym…
