论文摘要
彻底研究了（5 + 1）维相交厚的braneworld模型的重力定位。从I到V的五个独立提案的初步结果，重力被证明位于棕褐色中。特别是，对于从I到III的模型，仅通过分析确定零模式。另一方面，对于IV和V模型，全部获得了大量模式：在模型IV中确定了有限数量的大量状态，而模型V展示了无限但离散数量的大量巨大状态。考虑到引力模式的离散性意味着重力的空间并不意味着在共同的型号中，模型的normeliment and narmeldimilition and narbaudd singlimalimal and n harm of nharbe sissimalimal and In the nabled normalimalimal and Is viv and v。总而言之，还讨论了由模型III和IV构建的球模型的现象学含义。根据这样的整体分类，如果内部空间是一个球体，则显示IV模型显示出可正常的模式。更相关的是，对于从模型III组装的球体模型，鉴定出牛顿限制一致的微妙特性。
The localization of gravity for (5 + 1)-dimensional intersecting thick braneworld models is thoroughly investigated. Departing from preliminary results for five independent proposals, from I to V, gravity is shown to be localized in the brane. In particular, for models from I to III, only the zero modes are analytically determined. On the other hand, for models IV and V, massive modes are all obtained: a finite number of massive states is identified for model IV, while an infinite but discrete number of massive states bounded from below is exhibited by model V. Considering that the discreteness of the graviton modes implies that gravity does not propagate in the co-dimensions, the naked singularities of models IV and V, at edges of space, are made harmless. To conclude, the phenomenological implications for sphere models, constructed out of models III and IV, are also discussed. According to such an overall classification, if the internal space is a sphere, model IV is shown to exhibit normalizable modes. More relevantly, for the sphere model assembled out of model III, the subtle property of reproducing a consistent Newtonian limit is identified.
