Duality of Super D-brane Actions in Type II Supergravity Background

چکیده
We show that supersymmetric and κ-symmetric Dp-brane actions in type II supergravity background have the same duality transformation properties as those in a flat Minkowskian background. Specially, it is shown that the super D-string transforms in a covariant way while the super D3-brane is self-dual under the SL(2, Z) duality. Also, the D2-brane and the D4-brane transform in ways expected from the relation between type IIA superstring theory and M-theory. The present study proves that various duality symmetries, which were originally found in the flat background field, are precisely valid even in the curved background geometry.

It is shown in a quantum-mechanically exact manner that a supersymmetric and κsymmetric D-string action in a general type IIB supergravity background is transformed to a form of the type IIB Green-Schwarz superstring action with the SL(2, Z) covariant tension through an S-duality transformation. This result precisely proves a conjecture mentioned previously that the SL(2, Z) S-duality of a supe...
متن کاملDuality of Super D-brane Actions in General Type II Supergravity Background
We examine duality transformations of supersymmetric and κ-symmetric Dp-brane actions in a general type II supergravity background where in particular the dilaton and the axion are supposed to not be zero or a constant but a general superfield. Due to non-constant dilaton and axion, we can explicitly show that the dilaton and the axion as well as the two 2-form gauge potentials transform as dou...
متن کاملS duality and dyonic p-brane solutions in type II string theory.
We show how a solitonic “magnetically” charged p-brane solution of a given supergravity theory, with the magnetic charge carried by an antisymmetric tensor gauge field, can be generalized to a dyonic solution. We discuss the cases of ten-dimensional and elevendimensional supergravity in more detail and a new dyonic five-brane solution in ten dimensions is given. Unlike the purely electrically o...
متن کاملFermions, T-duality and effective actions for D-branes in bosonic backgrounds
We find the effective action for any D-brane in a general bosonic background of supergravity. The results are explicit in component fields up to second order in the fermions and are obtained in a covariant manner. No interaction terms between fermions and the field f = b+F , characteristic of the bosonic actions, are considered. These are reserved for future work. In order to obtain the actions...
متن کاملThe Super D9-Brane and its Truncations
We consider two inequivalent truncations of the super D9–brane: the “Heterotic” and the “Type I” truncation. Both of them lead to an N = 1 nonlinear supersymmetrization of the D = 10 cosmological constant. The propagating degrees of freedom in the Heterotic and Type I truncation are given by the components of a D = 10 vector multiplet and a single Majorana-Weyl spinor, respectively. As a by-pro...
