论文摘要

我们证明,如果具有扭曲的喉咙和抗烟叶的IIB弦理论的通常现象学压缩是有意义的,那么必须存在4D中的球形brane贝壳,这些球形壳被过多地充电。它们对应于经典的过度对象,但没有通常的裸奇异物。这些物体是由D3粒子制成的,这些粒子会在4D中稳定在有限的半径上的球形5型玻璃体中,其内部与超对称广告的真空相对应。人们可以将这些贝壳视为稳定的棕色teitelboim气泡。我们发现,这些对象可以明显大于弦量表,具体取决于扭曲的紧凑型细节。

We demonstrate that, if the usual phenomenological compactifications of IIB string theory with warped throats and anti-branes make sense, there must exist spherical brane shells in 4d that are overcharged. They correspond to classical over-extremal objects but without the usual naked singularities. The objects are made from D3-particles that puff into spherical 5-branes that stabilise at finite radii in 4d and whose inside corresponds to the supersymmetric AdS vacuum. One can think of these shells as stabilised Brown-Teitelboim bubbles. We find that these objects can be significantly larger than the string scale depending on the details of the warped compactification.
