Near-side Δη Correlations of High image Hadrons from STAR Original Research Article

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 dataset will be presented. This extends previous measurements where 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 are presented.
