关于超对称AdS $_4$定向折叠真空

On supersymmetric AdS$_4$ orientifold vacua

Fernando Marchesano, Eran Palti, Joan Quirant, Alessandro Tomasiello

摘要:

在这项工作中,我们研究了10维解的IIA型弦论的形式AdS $_4$ x $X_6$,其中包含orientifold平面和保持N=1超对称。特别是,我们考虑的解决方案,表现出一些关键功能的四维DGKT建议紧化的卡-丘流形通量,并在这个意义上可以被认为是他们的十维隆起。我们专注于超对称方程和Bianchi身份,并找到解决方案,这些是有效的在两个衍生物的水平和一阶的膨胀参数,这是有关的AdS宇宙学常数。这类解是这样的:背景度规从Ricci平坦的1变形为1,表现出SU(3)xSU(3)结构,并诱导出声子梯度和翘曲因子。

英文摘要:

In this work we study ten-dimensional solutions to type IIA string theory of the form AdS$_4$ x $X_6$ which contain orientifold planes and preserve N=1 supersymmetry. In particular, we consider solutions which exhibit some key features of the four-dimensional DGKT proposal for compactifications on Calabi-Yau manifolds with fluxes, and in this sense may be considered their ten-dimensional uplifts. We focus on the supersymmetry equations and Bianchi identities, and find solutions to these that are valid at the two-derivative level and at first order in an expansion parameter which is related to the AdS cosmological constant. This family of solutions is such that the background metric is deformed from the Ricci-flat one to one exhibiting SU(3)xSU(3)-structure, and dilaton gradients and warp factors are induced.
