  Two-particle azimuthal correlations have allowed detailed study of the
modification to di-jets in the hot, dense medium created in RHIC collisions.
Light can be shed by such correlations on many novel effects discovered at RHIC
such as the enhanced p/pi ratio and conical structure of events with energy
loss. Using pi0 triggers to reduce the effect of recombination we utilize
high-pT correlations to explore the away-side structure.
