解构D0-D6系统

Deconstructing the D0-D6 system

Alejandra Castro, Joan Simon

摘要:

在余维为1的边界稳定壁所限定的STU模型中,我们找到了带有D 0和D 6膜荷的两中心超对称解的完全经典模空间。U-对偶保证了我们的结论对任何具有负四次不变量的BPS态都成立。分析明确表明,边际稳定性的条件,即可积性条件,一般不足以提供一个规则的超重力解在这个模型。

英文摘要:

We find the complete classical moduli space of two-centered supersymmetric solutions carrying D0 and D6 brane charge in the STU model delimited by walls of marginal stability of co-dimension one. U-duality guarantees our conclusions hold for any BPS state with negative quartic invariant. The analysis explicitly shows that the conditions of marginal stability, i.e. the integrability conditions, are generically insufficient to provide a regular supergravity solution in this model.
