New BPS Wilson loops in $\mathcal N \textbf{= 4}$ circular quiver Chern-Simons-matter theories

Understand

We construct new families of 1/4 BPS Wilson loops in circular quiver $\mathcal N=4$ superconformal Chern-Simons-matter (SCSM) theories in three dimensions.

• They are defined as the holonomy of superconnections that contain non-trivial couplings to scalar and fermions, and cannot be reduced to block-diagonal matrices.
• Consequently, the new operators cannot be written in terms of double-node Wilson loops, as the ones considered so far in the literature.
• For particular values of the couplings the superconnection becomes block-diagonal and we recover the known fermionic 1/4 and 1/2 BPS Wilson loops.
