On $\mathcal{N}=4$ supersymmetry enhancements in three dimensions

Benjamin Assel, Yuji Tachikawa, Alessandro Tomasiello

We introduce a class of 3d theories consisting of strongly-coupled $\mathcal{N}=4$ systems coupled to $\mathcal{N}=3$ Chern-Simons gauge multiplets, which exhibit ${\mathcal N}=4…
