摘要:

研究了三维$\mathcal{N}=6$超共形Chern-Simons理论中点状威尔逊圈的小变形.通过对点状威尔逊圈进行圈变量幂的泰勒展开,得到了pp波背景下对应于对偶IIA弦论激发弦态的BPS算符.威尔逊圈的BPS条件既约束环变量又约束泰勒展开式中得到的算子形式。

英文摘要:

We consider the small deformation of the point-like Wilson loop in the 3-dimensional $\mathcal{N}=6$ superconformal Chern-Simons theory. By Taylor expansion of the point-like Wilson loop in powers of the loop variables, we obtain the BPS operators that correspond to the excited string states of the dual IIA string theory on the pp wave background. The BPS conditions of the Wilson loop constrain both the loop variables and the forms of the operators obtained in the Taylor expansion.
