弦论中非超对称吸引子的稳定性

On The Stability of Non-Supersymmetric Attractors in String Theory

Suresh Nampuri, Prasanta K. Tripathy, Sandip P. Trivedi

摘要:

研究了Calabi-Yau流形上的IIA型紧化中的非超对称吸引子。确定一个吸引子是稳定的还是不稳定的,一般需要复杂的代数分析。我们表明,使用群论技术,这种分析可以大大简化,可以减少到解决一个简单的例子,如STU模型。对于具有D 0-D4膜电荷的吸引子,确定稳定性需要在无质量场中将有效势扩展到四次阶。我们得到了这些项的全部。对于带D 0-D 6膜荷的吸引子,我们发现存在解的模空间,并且得到的吸引子是稳定的.我们的分析仅限于两个导数作用。

英文摘要:

We study non-supersymmetric attractors obtained in Type IIA compactifications on Calabi Yau manifolds. Determining if an attractor is stable or unstable requires an algebraically complicated analysis in general. We show using group theoretic techniques that this analysis can be considerably simplified and can be reduced to solving a simple example like the STU model. For attractors with D0-D4 brane charges, determining stability requires expanding the effective potential to quartic order in the massless fields. We obtain the full set of these terms. For attractors with D0-D6 brane charges, we find that there is a moduli space of solutions and the resulting attractors are stable. Our analysis is restricted to the two derivative action.
