AI总结:

本文提出天体Regge理论,通过分析散射幅的解析性质,定义了天体Regge极限,并确定了与本体幅极点和不连续性相关的CFT数据。

摘要:

利用散射幅的解析性质,我们提供了一种等价但不同的标准Mellin变换的定义,用于获得天体关联函数。从这种表示中,我们识别出一个天体色散关系,将减少的关联函数与本体幅的极点和不连续性联系起来。通过与标准CFT情况的类比,我们定义了天体Regge极限,并以支配本体Regge极限的部分幅率确定相关的天体CFT数据。

英文摘要:

Exploiting the analytic properties of scattering amplitudes, we provide an alternative but equivalent definition of the standard Mellin transform used to obtain celestial correlation functions. From this representation, we identify a celestial dispersion relation that relates the reduced correlation function to the poles and discontinuities of the bulk amplitude, and we present a novel expansion for the celestial correlator from an integral transform of the Froissart-Gribov expansion on the bulk. By drawing an analogy with the standard CFT case, we define the celestial Regge limit and identify the relevant celestial CFT data in terms of the partial amplitudes governing the bulk Regge limit.
