摘要:

本文给出了平坦空间Jackiw-Teitelboim(JT)引力与任意量子场论耦合的散射问题的精确解。JT重力导致场理论散射振幅的重力修整。修饰的$S$矩阵的精确表达式以前被认为是一个新的UV渐近行为的可解例子,被称为渐近脆弱性。该敷料等效于初始量子场论的$T\bar{T}$变形。JT引力耦合到一个单一的无质量玻色子提供了一个有前途的行动制定的可积近似的世界片理论的约束弦在3D gluodynamics。我们还导出了修饰的$S$ -矩阵作为近$AdS_2$全息的平坦空间极限。我们表明,为了保持平坦的空间么正性的传统Schwarzian敷料的边界扩张需要稍微扩展。最后,我们提出了一个新的简单的表达式的平坦的空间振幅的大质量粒子的全息CFT的调制器。

英文摘要:

We present the exact solution for the scattering problem in the flat space Jackiw-Teitelboim (JT) gravity coupled to an arbitrary quantum field theory. JT gravity results in a gravitational dressing of field theoretical scattering amplitudes. The exact expression for the dressed $S$-matrix was previously known as a solvable example of a novel UV asymptotic behavior, dubbed asymptotic fragility. This dressing is equivalent to the $T\bar{T}$ deformation of the initial quantum field theory. JT gravity coupled to a single massless boson provides a promising action formulation for an integrable approximation to the worldsheet theory of confining strings in 3D gluodynamics. We also derive the dressed $S$-matrix as a flat space limit of the near $AdS_2$ holography. We show that in order to preserve the flat space unitarity the conventional Schwarzian dressing of boundary correlators needs to be slightly extended. Finally, we propose a new simple expression for flat space amplitudes of massive particles in terms of correlators of holographic CFT's.
