幂零Goldstino的弦论实现

String Theory Realizations of the Nilpotent Goldstino

Renata Kallosh, Fernando Quevedo, Angel M. Uranga

摘要:

我们详细描述了如何在四维orientifolded IIB弦模型的一个单一的反D3膜的频谱精确地再现了一个幂零手征超场的场内容,唯一的物理成分对应于费米子goldstino。特别是,我们明确地考虑一个单一的反D3膜上的O3平面翘曲的喉咙,诱导$(2,1)$通量。更一般的系统,包括几个反膜和其他orientifold平面也进行了讨论。这进一步证明了弦论中由于反膜的存在而非线性实现的超对称性可以用包括幂零超场的超对称理论来描述。的KKLT和相关的场景的德西特模量稳定,宇宙学和软超对称性打破条款的结构的影响进行了简要的讨论。

英文摘要:

We describe in detail how the spectrum of a single anti-D3-brane in four-dimensional orientifolded IIB string models reproduces precisely the field content of a nilpotent chiral superfield with the only physical component corresponding to the fermionic goldstino. In particular we explicitly consider a single anti-D3-brane on top of an O3-plane in warped throats, induced by $(2,1)$ fluxes. More general systems including several anti-branes and other orientifold planes are also discussed. This provides further evidence to the claim that non-linearly realized supersymmetry due to the presence of antibranes in string theory can be described by supersymmetric theories including nilpotent superfields. Implications to the KKLT and related scenarios of de Sitter moduli stabilization, to cosmology and to the structure of soft SUSY-breaking terms are briefly discussed.
