New symplectic singularities from $SU(2)$ gauge theories
Families of $\mathrm{Sp}(1)\simeq\mathrm{SU}(2)$ gauge theories with eight supercharges are found to have a Higgs branch which is an isolated symplectic singularity. These are, in some sense, the most ``minimal''gauge theories as they only Higgs to a trivial theory. The matter content is $N$ fundamental half-hypermulti...
