AdS中动量空间标量振幅的研究

An étude of momentum space scalar amplitudes in AdS

Soner Albayrak, Chandramouli Chowdhury, Savan Kharel

摘要:

本文研究了用动量空间方法计算Anti-de Sitter空间中标量振幅的方法。我们表明,Arkani-Hamed,Benincasa和Postnikov推导的宇宙学波函数的算法可以直接用于动量空间中的AdS跃迁振幅,从而可以绕过体点积分。我们证明了这种方法在AdS的效用,在树和循环级别提出了几个明确的结果。

英文摘要:

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.
