Abstract
Measurements of the inclusive yields of pi0 mesons in p+p and d+Au collisions at center of mass energy sqrt(s_NN)=200 GeV and pseudorapidity <eta>=4.00 (d beam direction) are reported. The yield for p+p collisions is in general agreement with perturbative QCD calculations. The d+Au yield is in agreement with a calculation which models the Au nucleus as a Color Glass Condensate for forward particle production. The nuclear modification factor derived from the inclusive yields is qualitatively consistent with models which suppress the gluon density in nuclei.
