论文摘要
我们考虑了引力相互作用的高阶发条理论，从而将许多引力与TEV强度耦合在一起，但尽管如此，在不需要DiLaton的情况下产生了普朗克量表耦合至关重要的。结果表明，该框架自然地将自己放在五维几何形状上，我们发现了这种解构的4D引力发条模型的5D连续版本。此外，发条图片与特定的重力群有关，在5D框架中看起来像是Braneworld模型，Randall-Sundrum模型是一种特殊情况。更一般而言，引力发条会导致标量刺激的Braneworld模型家族，其中标量不是Dilaton。
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.
