Kaluza-Klein supergravity on AdS3 × S3
Abstract
We construct a Chern-Simons type gauged N = 8 supergravity in three spacetime dimensions with gauge group SO(4) × Tinfty over the infinite dimensional coset space SO(8,infty)/((SO(8) × SO(infty)), where Tinfty is an infinite dimensional translation subgroup of SO(8,infty). This theory describes the effective interactions of the (infinitely many) supermultiplets contained in the two spin-1 Kaluza-Klein towers arising in the compactification of N = (2,0) supergravity in six dimensions on AdS3 × S3 with the massless supergravity multiplet. After the elimination of the gauge fields associated with Tinfty, one is left with a Yang Mills type gauged supergravity with gauge group SO(4), and in the vacuum the symmetry is broken to the (super-)isometry group of AdS3 × S3, with infinitely many fields acquiring masses by a variant of the Brout-Englert-Higgs effect.
