N=4 SYM中sl（2）子扇区之外的包裹校正、互易性和BFKL
Wrapping corrections, reciprocity and BFKL beyond the sl(2) subsector in N=4 SYM
摘要：
我们考虑N=4 SYM和一类自旋N，长度为3，扭曲算子超出了研究得很好的sl（2）子扇区。它们可以用三个胶子算符在单圈上识别。在强耦合时，它们与AdS 5中具有两个自旋的自旋弦相关联。我们利用Y系统计算了主导弱耦合四圈缠绕修正对它们的反常维数。结果以闭合形式写成自旋N的函数。我们结合包裹校正与已知的四圈渐近Bethe Answer贡献，并分析特殊限制的自旋N。特别是，在大N，我们证明了广义Gribov-Lipatov互惠持有。在负非物理自旋下，我们提出了一个简单的BFKL方程来预测最右边的导极。
英文摘要：
We consider N=4 SYM and a class of spin N, length-3, twist operators beyond the well studied sl(2) subsector. They can be identified at one-loop with three gluon operators. At strong coupling, they are associated with spinning strings with two spins in AdS5. We exploit the Y-system to compute the leading weak-coupling four loop wrapping correction to their anomalous dimension. The result is written in closed form as a function of the spin N. We combine the wrapping correction with the known four-loop asymptotic Bethe Ansatz contribution and analyze special limits in the spin N. In particular, at large N, we prove that a generalized Gribov-Lipatov reciprocity holds. At negative unphysical spin, we present a simple BFKL-like equation predicting the rightmost leading poles.
