Strong-coupling results for $\mathcal{N}=2$ superconformal quivers and holography

Understand

We consider $\mathcal{N}=2$ superconformal quiver gauge theories in four dimensions and evaluate the chiral/anti-chiral correlators of single-trace operators.

• We show that it is convenient to form particular twisted and untwisted combinations of these operators suggested by the dual holographic description of the theory.
• The various twisted sectors are orthogonal and the correlators in each sector have always the same structure, as we show at the lowest orders in perturbation theory with Feynman diagrams.
• Using localization we then map the computation to a matrix model.
