由BES/FRS方程得到的双圈广义尺度函数
The 2-loop generalized scaling function from the BES/FRS equation
摘要：
我们将BES/FRS方程表示为快度空间中的函数方程，并在$\ell=j/4g$保持有限的情况下进行了强耦合展开。我们得到的结果是一致的，与以前的计算在树级和一个循环，这是不同于两个循环计算在0805.4615由一项奇异的$\ell=0$。
英文摘要：
We formulate the BES/FRS equation as a functional equation in the rapidity space and perform its strong coupling expansion in the limit when $\ell=j/4g$ is kept finite. We obtain a result which is consistent with the previous calculations at tree level and one loop and which differs from the two-loop calculation in 0805.4615 by a term singular at $\ell=0$.
