压缩Sasaki-Einstein流形上的IIB型超引力

Type IIB supergravity on squashed Sasaki-Einstein manifolds

Davide Cassani, Gianguido Dall'Agata, Anton F. Faedo

摘要:

在一般的5维压缩Sasaki-Einstein流形上,给出了IIB型超引力的一个相容的N=4 Kaluza-Klein截断.我们的约化分析通过规范/引力对应,使所有且只有超引力模与相关共形理论的普适规范扇区保持对偶。简化的5维模型显示出显著的特征:它包括零模以及内部流形上的卡鲁扎-克莱因算子的大量迭代;它包含与非阿贝尔规范群下带电向量对偶的张量场;它除了具有超对称真空外,还具有非超对称AdS真空的标量势。

英文摘要:

We provide a consistent N=4 Kaluza-Klein truncation of type IIB supergravity on general 5-dimensional squashed Sasaki-Einstein manifolds. Our reduction ansatz keeps all and only the supergravity modes dual to the universal gauge sector of the associated conformal theories, via the gauge/gravity correspondence. The reduced 5-dimensional model displays remarkable features: it includes both zero-modes as well as massive iterations of the Kaluza-Klein operators on the internal manifold; it contains tensor fields dual to vectors charged under a non-abelian gauge group; it has a scalar potential with a non-supersymmetric AdS vacuum in addition to the supersymmetric one.
