KaluzaKlein supergravity on AdS_{3} × S^{3}
Abstract
We construct a ChernSimons type gauged N = 8 supergravity in three spacetime dimensions with gauge group SO(4) × T_{infty} over the infinite dimensional coset space SO(8,infty)/((SO(8) × SO(infty)), where T_{infty} 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 spin1 KaluzaKlein towers arising in the compactification of N = (2,0) supergravity in six dimensions on AdS_{3} × S^{3} with the massless supergravity multiplet. After the elimination of the gauge fields associated with T_{infty}, 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 AdS_{3} × S^{3}, with infinitely many fields acquiring masses by a variant of the BroutEnglertHiggs effect.
