TL;DR
This paper derives a new nine-dimensional supergravity model with SO(2) gauging from ten-dimensional IIB supergravity, revealing novel Minkowski and domain wall vacua linked to D-branes.
Contribution
It introduces a generalized reduction method to obtain a maximally extended SO(2) gauged supergravity in D=9 with new vacua structures.
Findings
Scalar potential admits Minkowski and domain wall solutions
Vacua are related to type IIB D-branes
New type of domain wall solution discovered
Abstract
We show that a generalised reduction of D=10 IIB supergravity leads, in a certain limit, to a maximally extended SO(2) gauged supergravity in D=9. We show the scalar potential of this model allows both Minkowski and a new type of domain wall solution to the Bogomol'nyi equations. We relate these vacua to type IIB D-branes.
