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…
Exact WKB Analysis of N = 2 Gauge Theories
Sujay K. Ashok, Dileep P. Jatkar, Renjan R. John +2
We study N = 2 supersymmetric gauge theories with gauge group SU(2) coupled to fundamental flavours, covering all asymptotically free and conformal cases. We re-derive, from the co…
S-duality, triangle groups and modular anomalies in N=2 SQCD
S. K. Ashok, E. Dell'Aquila, A. Lerda +1
We study N = 2 superconformal theories with gauge group SU(N) and 2N fundamental flavours in a locus of the Coulomb branch with a Z_N symmetry. In this special vacuum, we calculate…
