We discuss azimuthal correlations in double inclusive hadron production in high energy dA collisions at RHIC. We argue that the leading logarithmic approximation is inadequate for description of experimental data. Realistic shape of the azimuthal correlation function is obtained only if we keep terms that are finite in the rapidity difference between the produced hadrons. Likewise, transverse momentum dependence of parton distribution functions in both deuteron and nucleus must be retained. We observe depletion of the back-to-back correlations in central dAu collisions in the forward direction consistent with the Color Glass Condensate predictions.
