- Descrição
- Chern-Simons AdS supergravity theories are gauge theories for the super-AdS group. These theories possess a fermionic symmetry which differs from standard supersymmetry. In this paper, we study five-dimensional Chern-Simons AdS supergravity in a Randall-Sundrum scenario with two Minkowski 3-branes. After making modifications to the $ D = 5 $ Chern-Simons AdS supergravity action and fermionic symmetry transformations, we obtain a $ \mathbb{Z}_{2} $-invariant total action $ S = \tilde{S}_{bulk} + S_{brane} $ and fermionic transformations $ \tilde{\delta}_{\epsilon} $. While $ \tilde{\delta}_{\epsilon} \tilde{S}_{bulk} = 0 $, the fermionic symmetry is broken by $ S_{brane} $. Our total action reduces to the original Randall-Sundrum model when $ \tilde{S}_{bulk} $ is restricted to its gravitational sector. We solve the Killing spinor equations for a bosonic configuration with vanishing $ su(N) $ and $ u(1) $ gauge fields.
