Abstract

Searching for the simplest non-abelian 2d gauge theory with
$\mathcal{N}=(0,2)$ supersymmetry and non-trivial IR physics, we propose a new
duality for $SU(2)$ SQCD with $N_f = 4$ chiral flavors. The chiral algebra of
this theory is found to be $\mathfrak{so}(8)_{-2}$, the same as in 4d
$\mathcal{N}=2$ $SU(2)$ gauge theory with four hypermultiplets.
