我们提出了一种新的高维机制来解决层次问题。弱尺度由普朗克尺度通过指数层次产生。然而，这个指数不是来自规范相互作用，而是来自背景度规（它是AdS(5)时空的一部分）。我们用两个3膜来演示该机制的一个简单的显式示例，其中一个包含标准模态场。这些模型的现象学是新的和戏剧性的。目前对超大额外维度的理论的限制都不适用。
We propose a new higher-dimensional mechanism for solving the hierarchy problem. The weak scale is generated from the Planck scale through an exponential hierarchy. However, this exponential arises not from gauge interactions but from the background metric (which is a slice of AdS(5) spacetime). We demonstrate a simple explicit example of this mechanism with two 3-branes, one of which contains the standard modal fields. The phenomenology of these models is new and dramatic. None of the current constraints on theories with very large extra dimensions apply.
