Structure Constants in N=2 Superconformal Quiver Theories at Strong Coupling and Holography.

In a four-dimensional N=2 superconformal quiver theory with gauge group SU(N)×SU(N) and bifundamental matter, we analytically obtain the exact strong-coupling behavior of the normalized 3-point correlators of single-trace scalar operators in the large-N limit using localization techniques. We then obtain the same strong-coupling behavior from the holographic dual using the AdS/CFT correspondence at the supergravity level. This agreement confirms the validity of the analytic strong-coupling results and of the holographic correspondence in a nonmaximally supersymmetric setup in four dimensions.
