Central charges and vacuum moduli of 2d $\mathcal{N}=(0,4)$ theories from class $\mathcal{S}$

We investigate 2d \mathcal{N}=(0,4) 𝒩 = ( 0 , 4 ) supersymmetric theories obtained from a topologically-twisted reduction of 4d \mathcal{N}=2 𝒩 = 2 class \mathcal{S} 𝒮 theories on a Riemann surface. This study addresses subtle aspects of central charges, unbroken gauge groups, an...
