D-branes and geometrical kappa-symmetry
نویسنده
چکیده
New extended superspaces associated with topological charge algebras of the D-brane are used to construct D-brane actions without worldvolume gauge fields. The actions are shown to be kappa-symmetric under an appropriately chosen right group action.

GENERALIZED ACTION PRINCIPLE and SUPERFIELD EQUATIONS OF MOTION for D=10 D–p–BRANES
The action for the D = 10 type II Dirichlet super–p–branes, which has been obtained recently, is reconstructed in a more geometrical form involving Lorentz harmonic variables. This new (Lorentz harmonic) formulation possesses κ–symmetry in an irreducible form and is used as a basis for applying a generalized action principle that provides the superfield equations of motion and clarifies the geo...
متن کاملCoincident (Super)–Dp–Branes of Codimension One
We consider properties of a covariant worldvolume action for a system of N coincident Dp– branes in D=(p+2) dimensional space–time (so called codimension one branes). In the case of N coincident D0–branes in D=2 we then find a generalization of this action to a model which includes fermionic degrees of freedom and is invariant under target–space supersymmetry and worldline kappa–symmetry. We fi...
متن کاملBrane Effective Actions, Kappa-Symmetry and Applications
This is a review on brane effective actions, their symmetries and some of their applications. Its first part covers the Green-Schwarz formulation of single M- and D-brane effective actions focusing on kinematical aspects: the identification of their degrees of freedom, the importance of world volume diffeomorphisms and kappa symmetry to achieve manifest spacetime covariance and supersymmetry, a...
متن کاملD-branes in Gepner models and supersymmetry
Boundary states corresponding to wrapped D-branes in Calabi-Yau compactifications of type II strings are discussed using Gepner models. In particular boundary conditions corresponding to D-0 branes and D-instantons in four dimensions are investigated. The boundary states constructed by Recknagel and Schomerus are analyzed in the light-cone gauge and the broken and conserved space-time supersymm...
متن کاملSuperbrane Actions and Geometrical Approach ∗
We review a generic structure of conventional (Nambu–Goto and Dirac–Born–Infeld– like) worldvolume actions for the superbranes and show how it is connected through a generalized action construction with a doubly supersymmetric geometrical approach to the description of super–p–brane dynamics as embedding world supersurfaces into target superspaces. During last years Dmitrij Vasilievich Volkov a...
