超对称性与微态几何中的包裹膜

Supersymmetry and Wrapped Branes in Microstate Geometries

Alexander Tyukov, Nicholas P. Warner

摘要:

本文研究了1/8-BPS微态几何中M2膜包裹时空圈的超引力反作用。我们表明,这样的膜包装一般会打破所有的超对称性。特别是,如果存在这样的包裹膜,但包裹膜的净电荷为零,那么所有的超对称性都将被打破。我们证明了如果M2膜包裹一个单圈,或者如果它们包裹几个具有相同取向的共线圈,那么解将是1/16-BPS,具有两个超对称性。我们评论这些结果如何与使用W膜理解1/8-BPS黑洞的微观结构。

英文摘要:

We consider the supergravity back-reaction of M2 branes wrapping around the space-time cycles in 1/8-BPS microstate geometries. We show that such brane wrappings will generically break all the supersymmetries. In particular, all the supersymmetries will be broken if there are such wrapped branes but the net charge of the wrapped branes is zero. We show that if M2 branes wrap a single cycle, or if they wrap a several of co-linear cycles with the same orientation, then the solution will be 1/16-BPS, having two supersymmetries. We comment on how these results relate to using W-branes to understand the microstate structure of 1/8-BPS black holes.
