Isometries in anti-de Sitter and Conformal Superspaces
P. Claus, J. Rahmfeld, H. Robins +2
We derive explicit forms for the superisometries of a wide class of supercoset manifolds, including those with fermionic generators in the stability group. We apply the results to…
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…
Near-Horizon Supergravity Superspace
Piet Claus
We present a construction of the superspace of maximally supersymmetric adS_{p+2} x S^{d-p-2} near-horizon geometry based entirely on the supergravity constraints of which the boso…
Superisometries of the adS*S Superspace
Piet Claus, Renata Kallosh
We find the superisometry of the near-horizon superspace, forming the superconformal algebra. We present here the explicit form of the transformation of the bosonic and fermionic c…
Symmetries of the Boundary of AdS_5 x S^5 and Harmonic Superspace
Piet Claus, Renata Kallosh, J. Rahmfeld
We study the boundary limit of the bulk isometries of AdS x S. The superconformal symmetry is realized on the coordinates of the AdS boundary, the fermionic superspace coordinates,…
Conformal Symmetry on World Volumes of Branes
Piet Claus, Renata Kallosh, Antoine Van Proeyen
We show how the anti-de Sitter isometries of a brane solution of supergravity theory produce superconformal invariance of their world-volume action. In this way linear as well as n…
Super M-brane actions in adS_4 x S^7 and adS_7 x S^4
Piet Claus
The world-volume action of the M2 brane and the M5-brane in an adS_4 x S^7 and a adS_7 x S^4 background is derived to all orders in anticommuting superspace coordinates. Contrary t…
Black Holes and Superconformal Mechanics
P. Claus, M. Derix, R. Kallosh +3
The dynamics of a (super)particle near the horizon of an extreme Reissner-Nordstrom black hole is shown to be governed by an action that reduces to a (super)conformal mechanics mod…
Vector-tensor multiplets
P. Claus, B. de Wit, M. Faux +3
We review the coupling of N=2 supergravity to vector-tensor multiplets, based on the method of superconformal multiplet calculus.
Conformal Theory of M2, D3, M5 and `D1+D5' Branes
P. Claus, R. Kallosh, J. Kumar +2
The bosonic actions for M2, D3 and M5 branes in their own d-dimensional near-horizon background are given in a manifestly SO(p+1,2) x SO(d-p-1) invariant form (p=2,3,5). These symm…
M 5-brane and superconformal (0,2) tensor multiplet in 6 dimensions
Piet Claus, Renata Kallosh, Antoine Van Proeyen
We present a gauge-fixed M 5-brane action: a 6-dimensional field theory of a self-interacting (0,2) tensor multiplet with 32 worldvolume supersymmetries. The quadratic part of this…
N=2 Supergravity Lagrangians with Vector-Tensor Multiplets
P. Claus, B. de Wit, M. Faux +3
We discuss the coupling of vector-tensor multiplets to N=2 supergravity.
Chern-Simons Couplings and Inequivalent Vector-Tensor Multiplets
P. Claus, B. de Wit, M. Faux +1
The off-shell vector-tensor multiplet is considered in an arbitrary background of N=2 vector supermultiplets. We establish the existence of two inequivalent versions, characterized…
Higher Covariant Derivative Pauli-Villars Regularization for Gauge Theories in the Batalin-Vilkovisky Formalism
P. Claus
The combined method of Higher Covariant Derivatives and Pauli-Villars regularization to regularize pure Yang-Mills theories is formulated in the framework of Batalin and Vilkovisky…
The Vector-Tensor Supermultiplet with Gauged Central Charge
P. Claus, B. de Wit, M. Faux +3
The vector-tensor multiplet is coupled off-shell to an N=2 vector multiplet such that its central charge transformations are realized locally. A gauged central charge is a necessar…
