Abstract

STAR preliminary results of di-hadron correlations versus φ_s, the trigger particle azimuthal angle relative to the constructed event plane are reported for mid-central Au+Au collisions and compared to central Au+Au as well as minimum bias d+Au collisions. The correlations are observed to vary with φ_s on both the near and away side of the trigger particle. The away-side correlation evolves from single- to double-peak with increasing φ_s. The near-side correlation is separated into 'jet' and 'ridge': the ridge is found to decrease with φ_s while the jet remains relatively constant.
