论文摘要
在本文中，我们探讨了在反DE保姆空间中计算标量振幅的动量空间方法。我们表明，Arkani-Hamed，Benincasa和Postnikov用于宇宙波形的算法可以直接用于动量空间中的ADS过渡幅度，从而绕过一个绕过散装点积分。我们通过在树和循环级别呈现几个明确的结果来证明AD中这种方法的实用性。
In this paper, we explore momentum space approach to computing scalar amplitudes in Anti-de Sitter space. We show that the algorithm derived by Arkani-Hamed, Benincasa, and Postnikov for cosmological wavefunctions can be straightforwardly adopted for AdS transition amplitudes in momentum space, allowing one to bypass bulk point integrations. We demonstrate the utility of this approach in AdS by presenting several explicit results both at tree and loop level.
