我们讨论了紧致Randall-Sundrum模型的全息解释的一些问题，该模型被认为是具有非线性实现的共形对称性的4D场论的对偶。我们对这个猜想进行了几次检验。特别地，我们证明了辐射子与背景4d度规共形耦合。我们还讨论了对Goldberger-Wise稳定电离子机制的解释。我们考虑了弱电击穿稳定辐射的情况，并讨论了味量子数的自然守恒问题。
We discuss some issues about the holographic interpretation of the compact Randall-Sundrum model, which is conjectured to be dual to a 4d field theory with non-linearly realized conformal symmetry. We make several checks of this conjecture. In particular, we show that the radion couples conformally to a background 4d metric. We also discuss the interpretation of the Goldberger-Wise mechanism for stabilizing the radion. We consider situations where the electroweak breaking stabilizes the radion and we discuss the issue of natural conservation of flavor quantum numbers.
