大自旋和大扭转下的普适反常维数

Universal anomalous dimensions at large spin and large twist

Apratim Kaviraj, Kallol Sen, Aninda Sinha

摘要:

本文研究了任意维CFTs($d\geq 3$)中大自旋($\ell$)和大扭曲($τ$)双迹算符的反常维数.利用解析共形bootstrap方法,我们证明了反常维数在极限$\ell\gg τ\gg 1$中是普适的。在推导过程中,我们得到了任意维全同标量四点函数共形块的近似封闭形式表达式。我们比较我们的结果与两个不同的计算全息,并找到完美的协议。

英文摘要:

In this paper we consider anomalous dimensions of double trace operators at large spin ($\ell$) and large twist ($τ$) in CFTs in arbitrary dimensions ($d\geq 3$). Using analytic conformal bootstrap methods, we show that the anomalous dimensions are universal in the limit $\ell\gg τ\gg 1$. In the course of the derivation, we extract an approximate closed form expression for the conformal blocks arising in the four point function of identical scalars in any dimension. We compare our results with two different calculations in holography and find perfect agreement.
