Integrated line-defect correlators in SCFTs at strong coupling
Lorenzo De Lillo, Marialuisa Frau, Alessandro Pini
We consider two four-dimensional SCFTs with gauge group : the SYM theory and the theory with four hypermultiplets in the fundamental represen…
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…
Chiral observables and S-duality in N = 2* U(N) gauge theories
S. K. Ashok, M. Billo, E. Dell'Aquila +4
We study N = 2* theories with gauge group U(N) and use equivariant localization to calculate the quantum expectation values of the simplest chiral ring elements. These are expresse…
Modular anomaly equations and S-duality in N=2 conformal SQCD
S. K. Ashok, M. Billó, E. Dell'Aquila +3
We use localization techniques to study the non-perturbative properties of an N=2 superconformal gauge theory with gauge group SU(3) and six fundamental flavours. The instanton cor…
S-duality and the prepotential in N=2* theories (I): the ADE algebras
M. Billo, M. Frau, F. Fucito +2
The prepotential of N=2* supersymmetric theories with unitary gauge groups in an Omega-background satisfies a modular anomaly equation that can be recursively solved order by order…
