具有体场和膜形场的光滑张力高余维膜世界
Smooth tensionful higher-codimensional brane worlds with bulk and brane form fields
摘要：
讨论了完全正则的余维-n膜世界解，其中膜的核被选择为无限体积的扁平体中的薄余维-（n-1）壳，并包含了一个位于膜上的Einstein-Hilbert项（Dvali-Gabadadze-Porrati模型）.为了支持这样的本地化的来源，我们丰富的真空结构的膜包含本地化的形式字段。我们发现，内部核心的大小的唯象约束似乎强加了一个上限膜张力。有限的横截体积光滑的解决方案也进行了讨论。
英文摘要：
Completely regular tensionful codimension-n brane world solutions are discussed, where the core of the brane is chosen to be a thin codimension-(n-1) shell in an infinite volume flat bulk, and an Einstein-Hilbert term localized on the brane is included (Dvali-Gabadadze-Porrati models). In order to support such localized sources we enrich the vacuum structure of the brane by the inclusion of localized form fields. We find that phenomenological constraints on the size of the internal core seem to impose an upper bound to the brane tension. Finite transverse-volume smooth solutions are also discussed.
