论文摘要
我们在Witten图的级别上启动对ADS空间中的结合状态散射的研究。对于具体性，我们将仅使用标量字段的案例重点放在案例上，并分析了几个基本图，这些图表更加一般图。我们获得了具有任意共形维度的梅林振幅的封闭形式表达式，这些幅度表现出有趣的行为。特别是，我们观察到某些树级绑定的状态witten图具有与广告中的环图相同的结构。
We initiate the study of bound state scattering in AdS space at the level of Witten diagrams. For concreteness, we focus on the case with only scalar fields and analyze several basic diagrams which more general diagrams reduce to. We obtain closed form expressions for their Mellin amplitudes with arbitrary conformal dimensions, which exhibit interesting behavior. In particular, we observe that certain tree-level bound state Witten diagrams have the same structure as loop diagrams in AdS.
