我们研究了R9，1中IIA型弦理论中NS-和D-膜相交的系统。我们证明了（3+1）维非超对称理论在相交处存在不稳定的真空，这种真空在膜构型参数空间的某些区域是长寿命的，而在另一些区域则消失.我们还评论了我们的构造与包裹在非紧卡-丘流形的圈上的D-和D ′-膜系统以及与其他相关系统的关系。
We study a system of intersecting NS- and D-branes in type IIA string theory in R9,1. We show that the (3+1)-dimensional non-supersymmetric theory at the intersection has unstable vacua which are long-lived in some regions of the parameter space of brane configurations, and disappear in others. We also comment on the relation of our construction to systems of D- and D¯-branes wrapped around cycles of non-compact Calabi–Yau manifolds and to other related systems.
