高自旋Wilson线AdS_3全息中的关联函数

Correlators in higher spin AdS_3 holography from Wilson lines with loop corrections

Yasuaki Hikida, Takahiro Uetoko

摘要:

利用sl(N)Chern-Simons规范理论中的开Wilson线,从体的观点研究了具有大中心荷的半经典区域中的二维W_N极小模型的关联函数子.我们扩展了以前的工作树层次的散装理论,将在本文中的循环校正。我们提供了一种正则化与回路图相关的发散的方法,使得具有两个标量和更高自旋流的三点函数与边界W_N对称性所确定的值一致。与处方,我们再现的保形重量的运营商对应的批量标量高达两个循环的显式的例子N= 2,3。

英文摘要:

We study the correlators of the 2d W_N minimal model in the semiclassical regime with large central charge from bulk viewpoint by utilizing open Wilson lines in sl(N) Chern-Simons gauge theory. We extend previous works for the tree level of bulk theory to incorporate loop corrections in this paper. We offer a way to regularize divergences associated with loop diagrams such that three point functions with two scalars and a higher spin current agree with the values fixed by the boundary W_N symmetry. With the prescription, we reproduce the conformal weight of the operator corresponding to a bulk scalar up to the two loop order for explicit examples with N=2,3.
