Abstract

Charged hadrons in 0.15⊥<4  GeV/c associated with particles of ptrig>4  GeV/c are reconstructed in pp and Au+Au collisions at √sNN=200  GeV. The associated multiplicity and p⊥magnitude sum are found to increase from pp to central Au+Au collisions. The associated pdistributions, while similar in shape on the nearside, are significantly softened on the awayside in central Au+Au relative to pp and not much harder than that of inclusive hadrons. The results, consistent with jet quenching, suggest that the awayside fragments approach equilibration with the medium traversed.
