  We show that geometric scaling is satisfied to good accuracy in the forward
region of d+Au collisions at RHIC. Scaling violations do show up, however, at
mid-rapidity, and the anomalous dimension of the small-x gluon distribution
evolves to near its DGLAP limit for transverse momenta of a few GeV. This
represents a first consistency check of RHIC deuteron-nucleus and HERA DIS
phenomenology, and of the universality of the underlying Color Glass Condensate
(CGC) theory, which describes both phenomena. It also reconciles successful
leading-twist LO and NLO perturbative QCD computations of mid-rapidity particle
production with small-x evolution. Finally, we introduce a new parameterization
for the anomalous dimension of the small-x gluon distribution which properly
reproduces known theoretical limits at large rapidity, at large virtuality, and
on the saturation boundary, and still fits the available data from d+Au
collisions at RHIC. We find indications that sub-asymptotic terms in the
rapidity-evolution of the anomalous dimension are large.
