Abstract

Systematic measurements of pseudorapidity (Δη) and azimuthal (Δϕ) correlations between high- p t charged hadrons in = 200 GeV Au+Au collisions are presented. An enhancement of correlated yield at large Δη on the near side is observed. This effect persists up to trigger p trig t ∼ 9 GeV/ c , indicating that it is associated with jet production. A more detailed analysis suggests distinct short-range and long-range components in the correlation.
