ABJ(M)理论中新的超对称威尔逊圈

New supersymmetric Wilson loops in ABJ(M) theories

V. Cardinali, L. Griguolo, G. Martelloni, D. Seminara

摘要:

本文在N= 6超对称Chern-Simons理论中提出了两类新的威尔逊圈算子.第一个是针对三维空间上的任意轮廓定义的,它类似于N=4 SYM中的Zarembo构造。第二种是二维球面上的任意曲线。在这两种情况下,我们都可以在威尔逊圈中加入一定的标量和费米子耦合,这样它就至少保留了两个超荷。一些以前已知的循环,特别是1/2 BPS圈,属于这一类,但我们指出了更多的特殊情况下,这是不知道的。它们可以提供ABJ(M)情况下规范/重力对应的进一步测试和有趣的可观测量,可以通过局部化精确计算

英文摘要:

We present two new families of Wilson loop operators in N= 6 supersymmetric Chern-Simons theory. The first one is defined for an arbitrary contour on the three dimensional space and it resembles the Zarembo's construction in N=4 SYM. The second one involves arbitrary curves on the two dimensional sphere. In both cases one can add certain scalar and fermionic couplings to the Wilson loop so it preserves at least two supercharges. Some previously known loops, notably the 1/2 BPS circle, belong to this class, but we point out more special cases which were not known before. They could provide further tests of the gauge/gravity correspondence in the ABJ(M) case and interesting observables, exactly computable by localization
