论文摘要
我们讨论了如何将非肌对称晶体纳入II型字符串理论的压缩中。我们特别关注$ su(3)\ times su(3)$结构歧管到四个维度的通量压实,以便使Spacetime填充DP-Branes的线性$ \ MATHCAL {n} = 1 $ superSymmemeTry自发地打破。抗DP-branes是此类麸皮的非常特殊的子集,但我们的分析是通用的。我们表明,通过包括nilpotent的手性多重型,可以将非超对称性麸皮的反应纳入标准4D $ \ MATHCAL {N} = 1 $ SuperGravity中。此类设置中的超对称性总是自发地破裂,并且非线性实现。特别地,这意味着,与以前认为的相反,Brane SuperSymmetry Breaking不能简单地用4D $ \ Mathcal {n} = 1 $ SuperGravity Theories中的D-Term描述。
We discuss how to incorporate non-supersymmetric branes in compactifications of type II string theories. We particularly focus on flux compactifications on $SU(3)\times SU(3)$ structure manifolds to four dimensions, so that a linear $\mathcal{N}=1$ supersymmetry is spontaneously broken by spacetime filling Dp-branes. Anti-Dp-branes are a very special subset of such branes but our analysis is generic. We show that the backreaction of non-supersymmetric branes can be incorporated into the standard 4d $\mathcal{N}=1$ supergravity by including a nilpotent chiral multiplet. Supersymmetry in such setups is always spontaneously broken and non-linearly realized. In particular this means that, contrary to what was previously thought, brane supersymmetry breaking cannot be simply described by a D-term in 4d $\mathcal{N}=1$ supergravity theories.
