On gauge/string correspondence and mirror symmetry

We consider a mirror dual of the Berkovits-Vafa A-model for the BPS superstring on AdS5 × S5 in the form of a deformed superconifold. Via geometric transition, the theory has a dual description as the hermitian gaussian one-matrix model. We show that the A-model amplitudes of AdS2 × S4 branes, breaking the superconformal symmetry as U(2,2|4) → OSp(4*|4), are evaluated in terms of observables in the matrix model. As such, upon the usual identification gYM2 = gs, these can be expanded as Drukker-Gross circular 1/2-BPS Wilson loops in the perturbative regime of Script N = 4 SYM.
