Modular properties of surface operators in N=2 SQCD
Sourav Ballav, Renjan Rajan John
We study half-BPS surface operators in N=2 supersymmetric QCD in four dimensions with gauge group SU(2) and four fundamental flavours. We compute the twisted chiral superpotential…

Surface operators in N=2 SQCD and Seiberg Duality
Sujay K. Ashok, Sourav Ballav, Marialuisa Frau +1
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 localiz…

Surface operators, dual quivers and contours
S. K. Ashok, S. Ballav, M. Billo' +5
We study half-BPS surface operators in four dimensional N=2 SU(N) gauge theories, and analyze their low-energy effective action on the four dimensional Coulomb branch using equivar…
