平面${\cal N}=4$ SYM理论的强耦合:一个全阶结果

Strong coupling for planar ${\cal N}=4$ SYM theory: an all-order result

Davide Fioravanti, Paolo Grinza, Marco Rossi

摘要:

我们提出了一个计划,用于确定一个广义的标度函数,即Sudakov因子在一个特殊的双标度极限的高自旋和大扭曲运营商属于$sl(2)$部门的平面${\cal N}=4$ SYM。特别是,我们明确地执行所有的顺序计算在强't Hooft耦合关于第一(贡献)广义尺度函数。此外,我们比较我们的渐近结果与数值解找到一个非常好的协议和数值评估的非渐近贡献。最后,我们说明了协议和预测的字符串方面。

英文摘要:

We propose a scheme for determining a generalised scaling function, namely the Sudakov factor in a peculiar double scaling limit for high spin and large twist operators belonging to the $sl(2)$ sector of planar ${\cal N}=4$ SYM. In particular, we perform explicitly the all-order computation at strong 't Hooft coupling regarding the first (contribution to the) generalised scaling function. Moreover, we compare our asymptotic results with the numerical solutions finding a very good agreement and evaluate numerically the non-asymptotic contributions. Eventually, we illustrate the agreement and prediction on the string side.
