TL;DR
This paper analyzes supergravity solutions for intersecting D-branes, revealing symmetry enhancements in certain configurations and comparing supergravity results with microscopic string analyses.
Contribution
It provides a detailed supergravity solution for D5-branes intersecting as an I1-brane and explores symmetry enhancements, extending the analysis to T-dual D4-D6 configurations.
Findings
Supergravity solutions match microscopic open-string analysis in near-horizon limit.
Symmetry enhancement from ISO(1,1) to ISO(1,2) occurs in I1-brane intersection.
T-dual D4-D6 configuration does not exhibit symmetry enhancement.
Abstract
We explore the supergravity solution of D5-branes intersecting as an I1-brane. In a suitable near-horizon limit the geometry is in qualitative agreement with that found in the microscopic open-string analysis as well as the NS5-brane analysis of Itzhaki, Kutasov and Seiberg. In particular, the ISO(1,1) Lorentz symmetry of the intersection domain is enhanced to ISO(1,2). The discussion is generalised to the T-dual configuration of a D4-brane intersecting a D6-brane. In this case the ISO(1,1) symmetry is not enhanced. This is true both in the supergravity approximation to the weakly coupled string theory and to the M-theory limit.
