Supersymmetric Wilson loops with general contours in ABJM theory

Understand

We consider general supersymmetric Wilson loops in ABJM model, i.e.

• Chern-Simons-matter theory in 2+1 dimensions with N=6 supersymmetry.
• They are so-called Zarembo-type: the Wilson loops of our interest have generic contours in spacetime, but the scalar field coupling is arranged accordingly so that there are unbroken supersymmetries.
• Based on the supermatrix formulation of Wilson loops by Drukker and Trancanelli, we construct explicitly 1/6-BPS Wilson loops and check that their expectation value is protected using perturbation up to two loops.
