Omar Foda, Yunfeng Jiang, Ivan Kostov, Didina Serban

摘要:

本文对平面N=4超对称Yang-Mills的标量扇区中局部规范不变单迹算子的三点函数进行了分类,其中至少包含一个su(3)算子.在两个su(3)和一个su(2)算子的情况下,树级3点函数可以用su(3)Bethe向量的标量积表示。此外,如果su(3)算子之一的第二级Bethe根是平凡的(设置为无穷大),则这个3点函数可以写成行列式形式。利用行列式表示,我们计算了半经典极限下的结构常数,当根的个数趋于无穷大时。

英文摘要:

We classify the 3-point functions of local gauge-invariant single-trace operators in the scalar sector of planar N=4 supersymmetric Yang-Mills involving at least one su(3) operator. In the case of two su(3) and one su(2) operators, the tree-level 3-point function can be expressed in terms of scalar products of su(3) Bethe vectors. Moreover, if the second level Bethe roots of one of the su(3) operators is trivial (set to infinity), this 3-point function can be written in a determinant form. Using the determinant representation, we evaluate the structure constant in the semi-classical limit, when the number of roots goes to infinity.
