我们考虑高阶发条理论的引力相互作用，其中一些引力子耦合在一起的TeV强度，但仍然产生普朗克尺度耦合到物质，而不需要一个引力子。结果表明，框架自然适合于一个五维的几何形状，我们发现这种解构的四维引力发条模型的5D连续版本。此外，发条图中的物质与特定的引力子耦合，在5D框架中看起来像是一个膜世界模型，兰德尔-桑德拉姆模型是一个特例。更一般地说，引力发条导致一族标量-张量膜世界模型，其中标量不是一个标量。
We consider the higher order clockwork theory of gravitational interactions, whereby a number of gravitons are coupled together with TeV strength, but nevertheless generate a Planck scale coupling to matter without the need for a dilaton. It is shown that the framework naturally lends itself to a five-dimensional geometry, and we find the 5D continuum version of such deconstructed 4D gravitational clockwork models. Moreover, the clockwork picture has matter coupled to particular gravitons, which in the 5D framework looks like a braneworld model, with the Randall-Sundrum model being a special case. More generally, the gravitational clockwork leads to a family of scalar-tensor braneworld models, where the scalar is not a dilaton.
