  Neutral pion (pi0) production is calculated in a leading order (LO)
perturbative QCD-based model in pp and dAu collisions at s^1/2=200 AGeV at
midrapidity. The model includes the transverse component of the initial parton
distribution. We compare our results for pp collision to experimental data at
RHIC energy. We repeat our calculation for the dAu collision and investigate
the interplay between shadowing and multiple scattering. In central $]dAu
collisions the influence of possible jet energy loss on cold nuclear matter is
discussed and numerical results are displayed.
