包装顺序的结构常数

Structure constants at wrapping order

Benjamin Basso, Vasco Goncalves, Shota Komatsu

摘要:

本文在六边形框架下研究了平面$\mathcal{N}$ = 4的Super-Yang-Mills理论中单迹算子的结构常数.当考虑到环绕在算子周围的虚粒子的影响时,由两个六边形形成三点函数的标准过程会产生发散。在本文中,我们解释了如何重新正规化这些分歧,并获得明确的预测,在领先的包装顺序,为一些结构常数,参数化的OPE的两个手性原色。我们测试我们的方法在弱耦合对四回路平面校正的BPS-BPS-小西OPE系数,最近在场论推导。在强耦合下,我们将我们的表达式与弦论中得到的三种半经典弦的结构常数进行了比较。

英文摘要:

We consider structure constants of single trace operators in planar $\mathcal{N}$ = 4 Super-Yang-Mills theory within the hexagon framework. The standard procedure for forming a three point function out of two hexagons develops divergences when the effects of virtual particles wrapping around the operators are taken into account. In this paper, we explain how to renormalize these divergences away and obtain definite predictions, at the leading wrapping order, for some of the structure constants that parameterize the OPE of two chiral primaries. We test our method at weak coupling against the four loop planar correction to the BPS-BPS-Konishi OPE coefficient, derived recently in the field theory. At strong coupling, we compare our expressions with the structure constants obtained in string theory for three semiclassical strings.
