Marco S. Bianchi, Luca Griguolo, Matias Leoni, Silvia Penati, Domenico Seminara

摘要:

本文研究了N=6超Chern-Simons物质理论中的一类BPS圆威尔逊圈,推广了通常的1/2-BPS圆.标量和费米子耦合依赖于两个形变参数,这些算符可以看作N=4 SYM中定义的DGRT纬度的ABJ(M)对应物。我们进行了一个完整的两个循环分析,他们的真空期望值,讨论了框架的依赖性,并提出了一个一般的关系,上同调等价的玻色算子。我们提出了一个全回路的建议,计算与1/2-BPS尖点有关的韧致辐射函数的广义威尔逊圈。当应用于我们的双循环结果时,它再现了已知的表达式。最后,我们评论的推广,这个建议的玻色子1/6-BPS的情况下。

英文摘要:

We study a family of circular BPS Wilson loops in N=6 super Chern-Simons-matter theories, generalizing the usual 1/2-BPS circle. The scalar and fermionic couplings depend on two deformation parameters and these operators can be considered as the ABJ(M) counterpart of the DGRT latitudes defined in N=4 SYM. We perform a complete two-loop analysis of their vacuum expectation value, discuss the framing dependence and propose a general relation with cohomologically equivalent bosonic operators. We make an all-loop proposal for computing the Bremsstrahlung function associated to the 1/2-BPS cusp in terms of these generalized Wilson loops. When applied to our two-loop result it reproduces the known expression. Finally, we comment on the generalization of this proposal to the bosonic 1/6-BPS case.
