Azimuthal correlations of high-pT charged hadron pairs from (di-)jet-fragmentation are studied at mid-rapidity in Au+Au collisions at vsNN=200 GeV. The distribution of jet-associated partner hadrons (1.0<pT<2.5 GeV/c) per trigger hadron (2.5<pT<4.0 GeV/c) is found to vary with collision centrality, both in shape and in yield, indicating a significant effect of the nuclear collision medium on the (di-)jet fragmentation process.
