3d mirror symmetry of braided tensor categories

Andrew Ballin, Thomas Creutzig, Tudor Dimofte +1

We study the braided tensor structure of line operators in the topological A and B twists of abelian 3d $N = 4$ gauge theories, as accessed via boundary vertex operator alg…

Line Operators in $U (1∣1)$ Chern-Simons Theory

Niklas Garner, Wenjun Niu

We analyze the non-semisimple category of line operators in Chern-Simons gauge theories based off the Lie superalgebra $gl (1∣1)$ . Our proposal is that the category of li…

Local Operators of 4d $N = 2$ Gauge Theories From the Affine Grassmannian

Wenjun Niu

We give a new, fully mathematical, construction of the space of local operators in the holomorphic-topological twist of 4d $N = 2$ gauge theories. It is based on computation…

How does the $S_{11}$ $N^{*} (890)$ state emerge from a naive $K$ matrix fit?

Yao Ma, Wen-Qi Niu, Yu-Fei Wang +1

We give a pedagogical analysis on $K$ matrix models describing the $π N$ scattering amplitude, in $S_{11}$ channel at low energies. We show how the correct use of analyticity in the…
