Description
We consider N=2 conformal quiver theories in four dimensions
which arise as orbifolds of N=4 Super Yang-Mills. Following the recent
Gaberdiel-Gopakumar derivation, we can explicitly construct a worldsheet
theory corresponding to the free limit of the 4-d gauge theory. Such
worldsheet description matches the planar spectrum with a special
distinction between the untwisted and twisted sector with respect to the
orbifold action.
Furthermore, for a special subclass of protected chiral operators we are
able to compute the two- and three-point functions both at weak and
strong coupling by using a localization approach. In particular the
strong coupling results are finally matched with proper dual
supergravity computations, determining a nice realization of AdS/CFT
correspondence in N=2 context.
