Abstract

We construct and analyse holographic duals to a class of four-dimensional = 1 SU(Nc) SQCD-like theories compactified on a circle with an R-symmetry twist. The setup originates from type IIB backgrounds previously proposed as duals to SQCD with Nf fundamental flavours. The U(1) R-symmetry is anomaly-...
