Contribution
It offers a new holographic framework for D-branes in NS fivebrane backgrounds, confirming prior indirect results and analyzing non-supersymmetric instabilities.
Findings
Verified properties of D-branes using holography
Identified instabilities in non-supersymmetric configurations
Described vacua of Little String Theory in linear dilaton backgrounds
Abstract
We study the dynamics of -branes in the near-horizon geometry of fivebranes. This leads to a holographically dual description of the physics of -branes ending on and/or intersecting -branes. We use it to verify some properties of such -branes which were deduced indirectly in the past, and discuss some instabilities of non-supersymmetric brane configurations. Our construction also describes vacua of Little String Theory which are dual to open plus closed string theory in asymptotically linear dilaton spacetimes.
