onstruction of novel BPS Wilson loops in three-dimensional quiver Chern-Simons-matter theories

In this paper, we construct novel Drukker-Trancanelli (DT) type BPS Wilson loops along infinite straight lines in燦=2,3爍uiver super Chern-Simons-matter (CSM) theories, Aharony-Bergman-Jafferis-Maldacena (ABJM) theory, and燦=4爋rbifold ABJM theory. There are several free complex parameters in the DT type BPS Wilson loops, and for Wilson loops in ABJM theory and燦=4爋rbifold ABJM theory there are supersymmetry enhancements at special values of the parameters. We check that the differences of the DT type and Gaiotto-Yin (GY) type Wilson loops are燪-exact with燪燽eing 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 Wilson loops in matrix models if they are still BPS quantum mechanically.
