چکیده
A geometrical formulation of the T-duality rules for type II superstring Ramond–Ramond fields is presented. This is used to derive the Wess-Zumino terms in superstring D-brane actions, including terms proportional to the mass parameter of the IIA theory, thereby completing partial results in the literature. For non-abelian world-volume gauge groups the massive type IIA D-brane actions contain non-abelian Chern–Simons terms for the Born–Infeld gauge potential, implying a quantization of the IIA cosmological constant.

T-Duality and Effective D-Brane Actions
T-duality realized on D-brane effective actions is studied from a pure worldvolume point of view. It is proved that invariance in the form of the DiracBorn-Infeld and Wess-Zumino terms fixes the T-duality transformations of the NS-NS and R-R background fields, respectively. The analysis is extended to uncover the mapping of global symmetries of the corresponding pair of D-branes involved in the...
متن کاملOn dimensional reductions of the M-9-brane
We discuss the relation of the M-9-brane with other branes via dimensional reductions, mainly focusing on their Wess-Zumino actions. It is shown that on dimensional reductions along three different directions, the Wess-Zumino action of the M-9-brane gives that of the D-8-brane, the IIA NS 9-brane, and the “KK-8A brane”, respectively, the last two of which were obtained via dualities. So, it is ...
متن کاملWess-Zumino actions and Dirichlet Boundary Conditions for Super p-branes with Exotic Fractions of Supersymmetry
The general solutions in the models of closed and open superstring and super p-branes with exotic fractions of the N = 1 supersymmetry are considered and the spontaneously broken character of the OSp(1, 2M) symmetry of the models is established. It is shown that extending these models by Wess-Zumino terms generates the Dirichlet boundary conditions for superstring and super p-branes. Using the ...
متن کاملA 10-form Gauge Potential and an M-9-brane Wess-zumino Action in Massive 11d Theory
We discuss some properties of an M-9-brane in “massive 11D theory” proposed by Bergshoeff, Lozano and Ortin. A 10-form gauge potential is consistently introduced into the massive 11D supergravity, and an M-9-brane Wess-Zumino action is constructed as that of a gauged σ-model. Using duality relations is crucial in deriving the action, which we learn from the study of a 9-form potential in 10D ma...
متن کاملD-branes in Type IIA and Type IIB theories from tachyon condensation
In this paper we will construct all D-branes in Type IIA and Type IIB theories via tachyon condensation. Then we propose form of Wess-Zumino term for non-BPS D-brane and we will show that tachyon condensation in this term leads to standard Wess-Zumino term for BPS D-brane.
