Description
Measurements of cross section modifications for hard processes that take place in a nuclear target provide information about the modification of parton densities in nuclei at low Bjorken $x$. This is interesting because it illuminates the physics of QCD at high parton density, and also because it provides a baseline against which the modification of cross ssections for hard processes in heavy ion collisions can be measured. PHENIX has now completed analysis of data from the 2008 d+Au RHIC run for production of quarkonia, open heavy flavor, and correlated high $p_{T}$ $\pi^{0}$ production at forward rapidty. In this talk we will discuss these results and what they convey about cold nuclear matter effects, and their implications for hot matter effects in Au+Au collisions.
