ABJ Wilson loops and Seiberg Duality

Shinji Hirano, Keita Nii, Masaki Shigemori

摘要:

我们研究了超对称${\cal N} = 6$超对称CSM理论、ABJ理论、有限$N_1$、$N_2$和$k$中的超对称威尔逊圈.这推广了我们以前对ABJ配分函数的研究。首先精确计算$U(N_1) \times U(N_2)$透镜空间矩阵模型中的威尔逊圈,然后进行解析延拓,$N_2$到$-N_2$,得到ABJ理论中的威尔逊圈,它是用形式级数给出的,只在微扰论中有效。通过一个Sommerwart-Watson型变换,我们提供了一个非微扰完成,使正式系列定义良好的所有耦合。这是由${\rm min}(N_1,N_2)$维积分给出的,它推广了ABJM理论配分函数的“镜像描述”。利用我们的结果,我们找到了原始和Seiberg对偶理论中的威尔逊圈之间的映射,并证明了对偶性。在我们的方法中,我们可以明确地看到如何微扰和非微扰的贡献,威尔逊圈下的对偶交换。对偶映射还得到了一个启发式的支持,但非常有用的论点的基础上膜配置,以及替代推导的基础上,卡普斯廷和威利特。

英文摘要:

We study supersymmetric Wilson loops in the ${\cal N} = 6$ supersymmetric $U(N_1)_k\times U(N_2)_{-k}$ Chern-Simons-matter (CSM) theory, the ABJ theory, at finite $N_1$, $N_2$ and $k$. This generalizes our previous study on the ABJ partition function. First computing the Wilson loops in the $U(N_1) \times U(N_2)$ lens space matrix model exactly, we perform an analytic continuation, $N_2$ to $-N_2$, to obtain the Wilson loops in the ABJ theory that is given in terms of a formal series and only valid in perturbation theory. Via a Sommerfeld-Watson type transform, we provide a nonperturbative completion that renders the formal series well-defined at all couplings. This is given by ${\rm min}(N_1,N_2)$-dimensional integrals that generalize the "mirror description" of the partition function of the ABJM theory. Using our results, we find the maps between the Wilson loops in the original and Seiberg dual theories and prove the duality. In our approach we can explicitly see how the perturbative and nonperturbative contributions to the Wilson loops are exchanged under the duality. The duality maps are further supported by a heuristic yet very useful argument based on the brane configuration as well as an alternative derivation based on that of Kapustin and Willett.
