本文在N = 2,3 π超共形Chern-Simons物质理论,Aharony-Bergman-Jafferis-Maldacena(ABJM)理论和N = 4轨道ABJM理论中构造了新的Drukker-Trancanelli(DT)型BPS Wilson环,并对其进行了分类.通常我们有四类Wilson环,它们都保持与BPS Gaiotto-Yin(戈伊)型Wilson环相同的超对称性。DT型BPS Wilson环中存在多个自由复参数,对于ABJM理论和N = 4轨道ABJM理论中的两类Wilson环,在参数的特定值处存在超对称性增强.我们检查了DT型和戈伊型威尔逊环的差异是Q精确的,其中Q是DT型和戈伊型威尔逊环都保留的一些超荷。这些结果对于计算矩阵模型中DT型Wilson环在量子力学上仍为BPS的情况下的真空期望值是有用的。
In this paper we construct and classify novel Drukker–Trancanelli (DT) type BPS Wilson loops along infinite straight lines and circles in N= 2, 3 quiver superconformal Chern–Simons-matter theories, Aharony–Bergman–Jafferis–Maldacena (ABJM) theory, and N= 4 orbifold ABJM theory. Generally we have four classes of Wilson loops, and all of them preserve the same supersymmetries as the BPS Gaiotto–Yin (GY) type Wilson loops. There are several free complex parameters in the DT type BPS Wilson loops, and for two classes of Wilson loops in ABJM theory and N= 4 orbifold ABJM theory there are supersymmetry enhancements at special values of the parameters. We check that the differences of the DT type and GY type Wilson loops are Q-exact with Q being some supercharges preserved by both the DT type and GY type Wilson loops. The results would be useful to calculate vacuum expectation values of the DT type Wilson loops in matrix models if they are still BPS quantum mechanically.
