Randall-Sundrum scenario from D=5, N=2 gauged Yang-Mills/Einstein/tensor supergravity

In this paper, a new locally supersymmetric two brane Randall-Sundrum model is constructed. The construction starts from a D=5, N=2 gauged Yang-Mills/Einstein/tensor supergravity theory with scalar manifold M=SO(1,1)×SO(2,1)/SO(2) and gauge group U(1)R×SO(2). Here, U(1)R is a subgroup of the R-symmetry group SU(2)R and SO(2) is a subgroup of the isometry group of M. Next, the U(1)R gauge coupling gR is replaced by gRsgn(x5) and the fifth dimension is compactified on S1/Z2. The conditions of local supersymmetry for the bulk plus brane system admit a Randall-Sundrum vacuum solution with constant scalars. This vacuum preserves N=2 supersymmetry in the AdS5 bulk and N=1 supersymmetry on the Minkowski 3-branes.
