Surface operators in 5d gauge theories and duality relations
S. K. Ashok, M. Billo, E. Dell'Aquila +4
We study half-BPS surface operators in 5d N=1 gauge theories compactified on a circle. Using localization methods and the twisted chiral ring relations of coupled 3d/5d quiver gaug…
Surface operators, chiral rings, and localization in N=2 gauge theories
S. K. Ashok, M. Billo, E. Dell'Aquila +4
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 rin…
Modular and duality properties of surface operators in N=2* gauge theories
S. K. Ashok, M. Billo, E. Dell'Aquila +3
We calculate the instanton partition function of the four-dimensional N=2* SU(N) gauge theory in the presence of a generic surface operator, using equivariant localization. By anal…
