Large-N localization and quiver CFT

The quiver CFT interpolates between N=4 SYM, which has a nice holographic dual, and N=2 super-QCD, which does not. The quiver itself is dual to AdS5xS5/Z2 with a b-flux (aka theta-angle) through the vanishing cycle of the orbifold. This wonderful picture is rather puzzling (why zero flux is pathological?) and calls for a quantitative test, hindered by the strong/weak coupling nature of holography. One possibility is to use localization, which gives access to strong coupling at substantial discount - it only remains to solve some matrix model at large-N. The strong-coupling solution, which I will describe, is in the remarkable qualitative agreement with the holographic dual, but is not devoid of puzzling features.
