摘要:

在本文中,我们调查的本地化超对称断裂膜,在涂抹近似,支持特定的非BPS真空。我们表明,对于广泛的一类边界条件,有没有通量真空时,膜是由一个真正的δ函数描述。而且,我们还发现,这个模糊解是唯一的具有规则膜轮廓的解。我们的设置包括一个非BPS的AdS_7解决方案在大规模IIA超重力与涂抹反D 6膜和通量T-对偶的IIB超重力的ISD通量。

英文摘要:

In this paper we investigate the localisation of SUSY-breaking branes which, in the smeared approximation, support specific non-BPS vacua. We show, for a wide class of boundary conditions, that there is no flux vacuum when the branes are described by a genuine delta-function. Even more, we find that the smeared solution is the unique solution with a regular brane profile. Our setup consists of a non-BPS AdS_7 solution in massive IIA supergravity with smeared anti-D6-branes and fluxes T-dual to ISD fluxes in IIB supergravity.
