Randall-Sundrum背景下的Chern-Simons AdS_5超引力

Chern-Simons AdS_5 supergravity in a Randall-Sundrum background

Richard S. Garavuso, Francesco Toppan

摘要:

陈-西蒙斯AdS超引力理论是超AdS群的规范理论。这些理论具有不同于标准超对称性的费米子对称性。在本文中,我们研究了五维Chern-Simons AdS超引力在Randall-Sundrum方案中的两个Minkowski 3-膜。对D = 5的Chern-Simons AdS超引力作用量和费米子对称变换作了修正,得到了Z_2不变的全作用量S = \tilde{S}_b ulk + S_brane和费米子变换\tilde δ_ε。当\tilde δ_ε \tilde{S}_b ulk = 0时,费米对称性被S_膜破缺。当\tilde{S}_b ulk被限制在它的引力扇区时,我们的总作用量减少到原来的Randall-Sundrum模型。我们求解了su(N)和u(1)规范场为零的玻色子位形的Killing旋量方程。

英文摘要:

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 Z_2-invariant total action S = \tilde{S}_bulk + S_brane and fermionic transformations \tildeδ_ε. While \tildeδ_ε\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.
