P.M. Cowdall, P.K. Townsend (Cambridge University)
TL;DR
This paper explores how specific solutions in gauged N=4 supergravity relate to supersymmetric vacua in 10-dimensional supergravity, revealing their connection to intersecting brane configurations.
Contribution
It demonstrates that domain wall and electrovac solutions in gauged N=4 supergravity correspond to supersymmetric Kaluza-Klein vacua of 10D supergravity, linked to intersecting branes.
Findings
Vacua are near-horizon geometries of intersecting branes
Solutions correspond to gauge groups SU(2) or SU(2)xSU(2)
Establishes a geometric interpretation of supergravity vacua
Abstract
Domain wall and electrovac solutions of gauged N=4 D=4 supergravity, with gauge group SU(2) or SU(2)xSU(2), are interpreted as supersymmetric Kaluza-Klein vacua of N=1 D=10 supergravity. These vacua are shown to be the near-horizon geometries of certain intersecting brane solutions.
