引力散射中的非微扰么正性

On Non-Perturbative Unitarity in Gravitational Scattering

Ivo Sachs, Tung Tran

摘要:

我们认为在广义相对论中,非微扰效应使Regge极限下的树能级引力子标量散射统一化。在普朗克能量下,入射引力子对背景几何的反反应产生非微扰平面波,这反过来又软化了紫外行为。我们的振幅,然后插入之间的微扰引力标量散射在低能量和经典的平面波散射的Regge限制。

英文摘要:

We argue that the tree-level graviton-scalar scattering in the Regge limit is unitarized by non-perturbative effects within General Relativity. At Planckian energy the back reaction of the incoming graviton on the background geometry produces a non-perturbative plane wave which, in turn, softens the UV-behavior. Our amplitude then interpolates between the perturbative graviton-scalar scattering at low energy and scattering on a classical plane wave in the Regge limit.
