Contribution
It provides a detailed analysis of D-brane configurations in AdS_3 backgrounds, including supersymmetric cases, using boundary state formalism and classical sigma models.
Findings
Identified supersymmetric D-brane configurations in AdS_3 backgrounds.
Determined the spacetime supersymmetry preserved by these D-branes.
Analyzed both bosonic and N=1 supersymmetric cases separately.
Abstract
We study the possible D-brane configurations in an AdS_3 x S^3 x T^4 background with a NS-NS B field. We use its WZW model description and the boundary state formalism, and we analyze the bosonic and the N=1 supersymmetric cases separately. We also discuss the corresponding classical open string sigma model. We determine the spacetime supersymmetry preserved by the supersymmetric D-brane configurations.
