Abstract We study half-BPS surface operators in four dimensional $${{{\mathcal {N}}}}=2$$ N=2 SU(N) gauge theories, and analyze their low-energy effective action on the four dimensional Coulomb branch using equivariant localization. We also study sur

Abstract We study half-BPS surface operators in 5d N $$ \mathcal{N} $$ = 1 gauge theories compactified on a circle. Using localization methods and the twisted chiral ring relations of coupled 3d/5d quiver gauge theories, we calculate the twisted chir

Abstract We study half-BPS surface operators in supersymmetric gauge theories in four and five dimensions following two different approaches. In the first approach we analyze the chiral ring equations for certain quiver theories in two and three dime

Abstract We calculate the instanton partition function of the four-dimensional N = 2 ⋆ $$ \mathcal{N}={2}^{\star } $$ SU(N) gauge theory in the presence of a generic surface operator, using equivariant localization. By analyzing the constraints tha

We study half-BPS surface operators in $$ \mathcal{N} $$ N = 2 supersymmetric QCD in four dimensions with gauge group SU(2) and four fundamental flavours. We compute the twisted chiral superpotential that describes the effective theory on the surface

We study half-BPS surface operators in N=2supersymmetric asymptotically conformal gauge theories in four dimensions with SU(N) gauge group and 2N fundamental flavours using localization methods and coupled 2d/4d quiver gauge theories. We show that co

We study N=2 super-conformal field theories in four dimensions that correspond to mass-deformed linear quivers with n gauge groups and (bi-)fundamental matter. We describe them using Seiberg-Witten curves obtained from an M-theory construction and vi
