BRST Quantization of a Particle in AdS_5
Piet Claus, Renata Kallosh, J. Rahmfeld
We perform the quantization of a massive particle propagating on AdS_5. We use the twistor formulation in which the action can be brought into a quadratic form. We construct the BR…
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…
A symplectic covariant formulation of special Kahler geometry in superconformal calculus
Piet Claus, Kor Van Hoof, Antoine Van Proeyen
We present a formulation of the coupling of vector multiplets to N=2 supergravity which is symplectic covariant (and thus is not based on a prepotential) and uses superconformal te…
