论文摘要
我们研究了一个小于一个小于1的单一扁平世界（或单堆麸皮）的蓝色世界情景。当额外的尺寸不小时，需要在勃板周围进行重力的定位，以重现可观察到的四维重力。我们专注于非划界额外维度的情况，在这种情况下，局部重力的可能性变得不平凡。我们表明，在大型的重力模型中，对于至少一个非伴随额外尺寸的CODIMENSION-2麸皮，无质量重力的定位是不可能的。有了在现场背景上进行的其他轻度假设，我们还表明，具有两个或多个非伴随额外尺寸的更高的编核心是不可能的。
We study the brane world scenario of a single brane (or a single stack of branes) with codimension higher than one. When the extra dimensions are not small, localization of gravity around the brane is needed in order to reproduce the observable four-dimensional gravity. We focus on the case of noncompact extra dimensions, where the possibility of localized gravity becomes non-trivial. We show that in large class of gravity models, localization of massless gravity is not possible for codimension-2 branes with at least one noncompact extra dimension. With additional mild assumptions on field backgrounds, we also show that it is not possible for higher codimensional branes with two or more noncompact extra dimensions.
