On a five-dimensional Chern-Simons AdS supergravity without gravitino

Based on recent discussions on the so-called unconventional supersymmetry, we propose a 5D Chern-Simons AdS-N-SUGRA formulation without gravitino fields and show that a residual local SUSY is preserved. We explore the properties of CS theories to find a solution to the field equations in a 5D manifold. With a Randall-Sundrum-type ansatz, we show that this particular dimensional reduction is compatible with SUSY, and some classes of 4D solutions are then analyzed.
