Abstract

We provide a detailed survey study of dihadron azimuthal angle (δφ) correlations in a broad range of transverse momentum (0.4 < p_T < 10 GeV/c) and centrality (0-92%) in Au+Au collisions at s_NN√ = 200 GeV. The evolution of the jet shape and yield with p_T seems to suggest two distinct components at the away-side pairs: a suppressed jet fragmentation component around δφ ̃ π, and a medium-induced components around |δφ-π| ̃ 1.1. The former dominates p_T > 5 GeV/c and the later dominates at p_T < 4 GeV/c.
