局部算子对威尔逊圈的半经典弦描述

A Semiclassical String Description of Wilson Loop with Local Operators

Makoto Sakaguchi, Kentaroh Yoshida

摘要:

讨论了无局部算子插入和有局部算子插入的圆威尔逊圈的半经典弦描述.通过考虑AdS_5 × S^5上IIB型弦论在相应经典解附近的半经典近似,计算了关于涨落的二次作用量。然后从威尔逊圈小变形的角度讨论了描述涨落的对偶对应算子。这一结果为AdS/CFT对应提供了新的证据。

英文摘要:

We discuss a semiclassical string description to circular Wilson loops without/with local operator insertions. By considering a semiclassical approximation of type IIB string theory on AdS_5 X S^5 around the corresponding classical solutions, quadratic actions with respect to fluctuations are computed. Then the dual corresponding operators describing the fluctuations are discussed from the point of view of a small deformation of the Wilson loops. The result gives new evidence for AdS/CFT correspondence.
