Systematic measurements of pseudorapidity (Δη) and azimuthal (Δϕ) correlations between high-pt charged hadrons and associated particles from the high statistics 200 GeV Au+Au and Cu+Cu datasets will be presented. In previous measurements differences in the near-side Δη correlation between central Au+Au and the lighter systems, d+Au and p+p, were observed, including a long-range near-side correlation in Au+Au collisions. Studies to characterize the properties of the long-range correlation will be presented.
