论文摘要
在这项工作中，我们获得了一个新的扭曲解决方案，用于在反de-sitter散装中使用5维$ f（r）$重力。重力作用中的较高曲率项已显示可修改通常的扭曲度量。这种修饰的新特征导致在可见的3-桥的基础有效理论中模量/辐射场的自然几何稳定，而无需任何外部稳定场。进一步表明，模量的稳定值解决了众所周知的仪表层次结构问题，而模型参数没有任何不自然的微调。在较高维度时空的背景下，这种新解决方案还可以在各种情况下开辟了新签名的可能性。
In this work, we obtain a new warped solution for a 5-dimensional $f(R) $ gravity in an anti de-Sitter bulk. The higher curvature term in the gravity action is shown to modify the usual warped metric. The novel feature of this modification leads to a natural geometric stabilization of the modulus/radion field in the underlying effective theory on the visible 3-brane without the need for any external stabilizing field. It is further shown that the stabilized value of the modulus resolves the well-known gauge hierarchy problem without any unnatural fine-tuning of the model parameters. This new solution also opens up the possibilities of new signatures in various scenarios formulated in the backdrop of higher dimensional space-time.
